How do I re-install the OS and keep all data?

I have K9 WebProtection and forgot which e-mail address I signed up with (as well as admin password..stupid I know). Today it blocked yahoo and google (it isn't supposed to block anything but adult material which we needed when my son still lived with us) and it shut off internet acces for 8 hours because I kept hitting refresh trying to figure out why its doing that. Well the only way to unstall it is to re-install the OS. I have over 10,000+ pics and 2,000+ songs that I dont want to loose. Not to mention Word Docs and Ppt presentations. Whats the best way of going about re-installing the OS? Maybe partioning the HD? But I dont know how to do that. Please provide me with the steps on how to do this (I have Time Capsule if that makes a difference)

Just to add to Thomas's good advice:

why would you think you'd lose them?

How do I cut out the vocals and keep the instrumentals

I recorded a track and I just want to keep the instumentals and discard the vocals. Is there a way to break it down and just discard the vocals and keep the instrumentals?

From a professionally recorded stereo recording (that's not what you originally said) you can possibly reduce the vocals

A better option would be to find a MIDI file of the song you want.

Deploy BPM application and keep all data of old tasks

Hi all,
Currently, whenever i redeploy bpm application to weblogic server, all tasks information saved in database will be changed (the value of state attribute will be changed to 9). So i think it's not good in Production environment. I want to configure to keep all data of old tasks whenever deploy again.
Does anyone knows the solution for this ?
Thanks.

Hi,
Do you mean when you re-deploy the BPM composite application?
Do you overwrite the older version of the composite or deploy as a new version?
If you deploy a newer version, your existing task information should remain as it is otherwise it'll change to stale...

James j,
You have a different problem. Your screenshot shows "The Adobe Flash plugin has crashed".

How do I export a video so I can still edit it in the future and have all data (no compression)

I am super new to Premiere Elements and video in general so my question is probably a no brainer. I am taking parts of a video and exporting them out so I can come back later and edit them. When I try this the dimension is changing even though I'm checking 1080x720. It's also losing quality. I'm a wedding photographer (not videoagrapher) and don't know the correct terminology to use. This is for a family wedding I did where I also experimented with video. Basically what I would like to do is take the "raw" clips and grab the scenes I want, export them and bring them back at a future time and edit them without losing quality.
I have tried researching this and am so frustrated. I just can't figure this out. Thank you in advance to anyone who can point me in the right direction.

Thanks for the reply. From your screenshot, I cannot be sure if you are using Premiere Elements 12 or 11 (very similar) on Windows. So, for now I will assume Premiere Elements 12 on Windows 7, 8, or 8.1 64 bit.
From your screenshot, it would appear that your source is
1920 x 1080 @ 23.976 progressive frames per second
So, you or the project should have set a project preset of
NTSC
DSLR
1080p
DSLR 1080p24
If the program was allowed to set the project preset based on the properties of the first video drag from Project Assets to Timeline, we can find out if it did it "right". Sometimes it does not. To do this...Edit Menu/Project Settings/General. And, if the Project Settings look like the following screenshot, the program set the project preset correctly:
If you do not see the above, then new project whose project preset you set manually before you import your video.
To do that...
In Expert workspace, File Menu/New/Project and Change Settings.
Change Settings to NTSC/DSLR/1080p/DSLR1080p24
Before exiting that area, be sure to have a check mark next to "Force Selected Project Settings on This Project" in the new project dialog.
Now the big question, what to export this TImeline to so that the export will be part of a family of exports to joint a grand project. If you know that all you want as the destination is NTSC DVD-VIDEO Widescreen on DVD disc, then you can export each TImeline as a DV AVI Widescreen file (Publish+Share/Computer/AVI with Presets = DV NTSC Widescreen. When all is said and done, all these DV AVI Widescreen files will be imported in a new Premiere Elements 12 NTSC DV Widescreen project for burn to with Publish+Share/Disc/DVD disc with NTSC _Widescreen_Dolby DVD preset.
Alternative way, if you had HD plans for this edited video on this Timeline, could be
a. Project Preset - set as before 1920 x 1080p24
b. Export as Publish+Share/Computer/AVCHD with Presets = MP4 - H.264 1920 x 1080 p24
c. Combine all the individual .mp4 into one grand project (project preset = 1920 x 1080p24) with a destination for
DVD-VIDEO Widescreen on DVD disc
or
AVCHD format on DVD disc
or
Blu-ray disc format on Blu-ray disc.
You wrote
In mpeg I used preset HDTV 1080p 29.97 high quality and it seems to save it just fine. But can I bring these files back in and edit with non-destructive editing?
This would be a Publish+Share/Computer/MPEG choice (MPEG2 HD.mpg 1920 x1080p29.97 versus what I described as an alternative Publish+Share/Computer/AVCHD choice (AVCHD.mp4 1920 x 1080p24). The project preset for the grand project might be:
for 1920 x 1080p29.97, NTSC/DSLR/1080p/DSLR1080p30 @ 29.97
for 1920 x 1080p24, NTSC/DSLR/1080p/DSLR1080p24
Irrespective of the frame rate along the line, in the end, burn to presets are standarded at @29.97 interlaced frames per second.
Please review and consider. If I did not explain clearly enough, please let me know, and I will rewrite if need be.
Thanks.

How can I Downgrade to Snow Leopard and keeping all 3rd party apps?

New to MacBookPro and really happy. With Lion...not so much. I want to downgrade to SL, however, apparently I must reformat the hard drive. Here´s the real question: If I have a backup of my entire HD with the user, docs and all the apps I have installed (on Lion), once I downgrade to Snow Leopard, can I just move all my apps from the back up disk I have made of my Lion-Running hard drive? In other words, How can I downgrade without having to reinstall every single third party app I have?

First, how new is this Mac? A Mac as a rule cannot boot to an older operating system version than that with which it was originally supplied. In other words, if this is a new MBP that came with Lion then you probably cannot get it to boot to SL.
Some applications (and I take it you do mean full "applications" rather than "apps" which are mobile device programs -- it helps to be clear o terminology) can just be dragged from place to place. Others, notably Adobe and Office, install things all over the place and unless you are good at finding hidden files with obscure names in 10 different places you will just have to re-install them.

How do I reinstall my operating system and keep my data?

I recently installed a new time capsule and created a network. I have a three year old iMac (early 2009) on this network and a Mac Book Pro (late 2011). In addition, I backed up iTunes and iPhoto libraries to an external drive, with the intention of erasing them from my internal HD, just before installing the time capsule.
Since making this change there have been a number of problems with the iMac. It freezes up frequently, and also opens and closes programs at will. For example, it reopens already closed windows on its own. Speakers shut themselves on and off. The mouse disappears. Going full screen with a movie enlarges the screen, but the moviie appears the same size in one corner. There are "flashes" of windows which open and close at lightening speed. All these problems are intermittent, but started within the past two weeks, after intalling time capsule. Most recently, I received an error message where a grey screen came over my open window and told me I had to restart my computer immediately.
iTunes also had a problem with launching itself over and over. I did a bit of searching the web and resolved it the following manner. It seems to have worked.
While ITunes was open I opened Terminal and typed: killall iTunes
This seems to have worked, but I include the information here to expound on the problems I've been having.
I have my system backed up to the time capsule, using time machine, and the above mentioned libraries are on a seperate hard drive. But is it possible to reinstall the operating system without losing documents and other personal stuff on my iMac? Is reinstalling the recommended fix for all this instability?
In addition to the above, my Mac Book Pro has also been running slower, with lots of pinwheels, since the network setup.
Thanks in advance for your help with this problem.

How can I change a mail account and keep all email?

Brought my G4 home after our business closed. I want to simply change my email account info from my work info to my personal info without losing any of the saved emails from work. Did that make sense? How can I do that? I tried just changing my email address and server settings but I can't get any mail, the program times out.
Thanks very much for any advice!
Cheers,
Jon

Jon, First Quit Mail, then I'd backup these two Mail folders, by right clicking on them in the Finder, then choose Archive/Compress.
Users/YourUserName/Library/Mail
Users/YourUserName/Library/Mail Downloads
(Could be a different folder here if you chose such in Mail Prefs)
Right click on that Mail folder, choose archive, you'll get everything in the folder, and the folder itself in a file called Mail.zip, move it to a safe place, same for the Mail Downloads folder... only the plist is separate.
/Users/YourUserName/Library/Preferences/com.apple.mail.plist
I think not getting the Mail is a different problem. Are they differen't ISP at work & Home?
Which Ports is it using?
IMAP or POP on both?

How can I create Folders in iPod and keep all bands & artists separate?

Hi guys,
How can I create folders for different artists and keep them separate? Is it somthing that I need to do in iTunes in my Mac or import them a certain way?
Anyone please,
Thanks in advance,
Zia

If you have the artist information entered in iTunes, then they should already be organized like that on iPod.
Go to music-->artists

HT1386 I have a new MacBook as my PC died and is it possible for me to sync my iPod to the mac and keep all my previous levels on the apps?

How do you preserve levels on apps when you are forced to sync to a new computer?

- Transfer iTunes purchases by:
- For other music you need a third-party program like one of those discussed here:
Copy music
- Connect the iPod to the computer and make a backup by right clicking on the iPod under Devices in iTunes and select Back Up.
- Restore the iPod from that backup
Note that the backup that iTunes makes does not include media like app and music.

I am new to Mac and am wondering if I make an Album in iPhoto by moving similar events that have been dated into the album will they just merge or will the events move into the album and keep their date

I am new to the MacBook Pro and am wondering if I make an Album in iPhoto by using events that have titles and dates will I loose the titles and dates??I had hoped to combine my ie. 2010 Trip pictures Grandchildren pictures etc but do not want to lose the dating of them.
What advice does anyone out there have for a program to add text to the pictures. I have been using Paint Shop on my PC but want to switch totally to the MAC
Thank you

1 - iPhoto is a database and there is a learning curve - it is all about photos and nothing about files - under teh help menu ==> iPhoto help watch the movies - that will help get you started more smoothly
2 - there never is a reason to go directly into the iPhoto library - do not do it (inclusing via the all images display in teh finder) - doing so can cause loss of data and photos
3 - preview or a third party editor can add text to photos
4 - events are very basic automatic automatic things and generallly it is best to leave them as buckets of photos and organize via albums and folders - and using keywords, faces and places and smart albums
5 - dates are part of the metadate stored in the EXIF fields of the photo - moving a photo will not affect that (but note that file managers like the finder do not look at the photo metadate - they look at teh file metadate which is seperate

HT204053 How can I have 3 iCloud accounts and keep all pictures, contacts, messages separate ?

I have one Apple account and would like to use iCloud. I would like to have 3 iCloud accounts. One for each person in my family. One person has an iPhone3gs, one has a iPhone 4, and I have a iPad and an iPhone 4s. I would like all pictures, contacts, messages to stay separate for each user.
Can this be done?

Welcome to the Apple community.
To begin with, I would like to try to explain Apple's confusing nomenclature in regard to iCloud.
Apple have called the whole cloud thing iCloud, there are a number of features under the iCloud umbrella, some of which require their own login. iTunes is one of these, another is what Apple have unfortunately also called iCloud.
You can use the same Apple ID (account) to login to both iCloud and iTunes, but you don't need to and often users will login to each service using a different ID.
The part that you need to remember is that the services available when you log into iCloud are completely different and unrelated to those when you log in to iTunes. Your iCloud login enables mail, contacts, calendars, find my phone, Back to My Mac, Documents & Data sharing and photosstream, it does not affect any of your iTunes services.
To avoid confusion when discussing your problem, when I mention iCloud, I am referring to the services under the iCloud login, Whereas I will refer to the whole cloud thing as The Cloud.
I suspect what you are wanting to do is all share the same account for iTunes and each use your own accounts for iCloud.

I've been sharing my husbands account for years and I now want to open my own account. How can I open my own account and keep all my contacts?

I've been sharing my husbands Apple ID for years and I now want to create my own Apple ID but how can I get all my information saved on my husbands Apple ID to my new Apple ID.

How do I un-install the update that disabled my add-on's that I depend highly upon?

Today I downloaded your update, THEN I was told that some programs I highly depend upon have been disabled, how do I un-install the update and get my functionality back for my programs. I was not having any problems until I downloaded the update. I am not happy. The programs involved in the order of there importance are Freecorder and U-tube Video Capture.

You can make Firefox '''Firefox 5.0''' look like Firefox 3.6.18, see numbered items 1-10 in the following topic [http://dmcritchie.mvps.org/firefox/firefox-problems.htm#fx4interface Fix Firefox 4.0 toolbar user interface, problems (Make Firefox 5.0, or 4.0.1, look like 3.6)].
'''Research your extensions''',
You might also find addition information on the extension's add-on page, some may have updates, some solutions may be found in the developer comments or user comments on the add-on, or on the "'''View all versions'''" link which is part of the '''Release notes''' at the bottom of the add-on page where you may find a compatible version available that is waiting for approval.
===Force Compatibility===
You can force 5.0 "compatibility" with the "[https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/ Compatibility Reporter]" extension, or with [http://kb.mozillazine.org/Extensions.checkCompatibility extensions.checkCompatibility] using about:config.
One of the nice things about having extensions is that you can disable them and still use Firefox, disabled extensions will still get update notices. Or maybe use another extension until the one you want is fixed or works for you.
===Restore an Earlier Version===
For those that really need an earlier version of Firefox, find your system and the Firefox version you want in releases, download and start the install.
* ftp://ftp.mozilla.org/pub/firefox/releases/
:or with the latest of version 3
* http://www.mozilla.com/firefox/all-older.html
When reinstalling Firefox from a download, Firefox must be down once the installation starts. When the installation finishes, don't let the install start firefox for you. Instead end the install and start Firefox in your normal manner, thus preventing creating a new profile which does not have your bookmarks cookies, etc (but your old profile would still be around and would).

How do I re-install the OS and keep all data?
