I have lost catalog, previews and slideshow

I made a slide show. When I wnet in to change something the pictures would not come up in either slideshow, library or develope. An Error box said something about the previews were corrupted. I looked up what to do (delete the previews and let it rebuild) It did not work. Now I am in a really big mess. Others of my pictures are a missing. All the pictures from the slide show are missing. I know that the originals are still on my computer but I need to get back to the slideshow and how it was set up. I need help really fast. The customer is expecting the corrected version of the slideshow in 2 days!

I realized when I wrote the note that details were being left out but I was almost afraid that I would scare people off, at least that is the way it seemed. I have been looking for an answer for days now and no one has answered. Thanks DJ.
I am running a PC on Microsoft Windows 7. I use Lightroom 4 upgraded to 4.4.
I am not a techy, I am a Grandmother that loves photography, and Lightroom, but for the life of me there are some parts of Lightroom that I just don’t understand.
I loaded and fixed up some pictures in Lightroom and then made a slide show from the pictures. The pictures are not mine, I am doing it for an organization. http://www.youtube.com/watch?v=W3ms3xlWgbE . When I went back in to make some corrections I got an error message.
I put the exact error message into Google, which said :"Lightroom encountered an error when reading from its preview cache and needs to quit. Lightroom will attempt to fix this problem the next time it launches". It never did fix itself so I found several sites that said I needed to delete the preview cash. Now this is where, to me, it gets complicated: I didn’t know where the preview cashe was so I put it in my programs and files search and to my surprise it showed me a bunch of catalogs that I didn’t even know that I had. I selected the one with the most recent activity on it and deleted the preview cashe. It didn’t seem to do anything, no error message, nothing. When I went back into the catalog that had the pictures and slide show in it, it seemed to be gone.
I understand that it may have deleted it but it has never attempted to rebuild it and now all of those pictures and their changes seem to no longer be in Lightroom. I am afraid to do anything else for fear that I will really screw things up.
Now that I am calming down a bit, just from finally making contacting with someone else about this, I do realize that the pictures being missing is another problem. Can I discuss this with you later?
Is this forum the only way to talk to you? I was afraid that what ever that delete was that I hit deleted a bunch of other pictures.

Full screen preview and slideshow are blurry / fuzzy

Hi folks-
I just upgraded from CS2 to CS4, in part to improve efficiency of selecting photos - I wanted the zoom and loupe features. Unfortunately a very basic function has been compromised and I'm hoping there's a solution: In both full-screen preview and slideshow the full-screen image is notably blurry. This is a problem for two reasons: 1. I can't judge pictures accurately by just flipping through them in full-screen mode (without zooming to 100% to see if they are well-focused). 2. I can't use Slideshow for, well, slideshows. I've had to resort to keeping another app (like Windows Picture Viewer) open just to be able to quickly flip through and evaluate images full-screen or to show slideshows.
I've tried setting all the options related to image quality (they mostly have to do with caching thumbnails and speeding 100% viewing); I've tried purging the cache files. Nothing helps.
Any ideas? Thanks!

It seems to me that there is something wrong with it.
I am trying Bridge CS4 as a viewer for my JPEG files.
I also noticed that the previews were fuzzy. I activated the high-quality previews as well as the option to generate the previews at screen size.
Here's what I noticed. I went to check out a specific photo that is quite sharp with a number of straight lines, angles, details, where it's very easy to detect a lack of sharpness. That photo immediately looked fuzzy to me, which didn't jive with my memory of it. I quickly opened it in other viewers, which displayed it as intended with all the expected sharpness.
So, I went through the settings to see where the problem could be and I immediately thought of checking the box to get software previews instead of hardware, restarted the app, purged the cache, tried again. There my photo had recovered its sharpness, or at least most of it. I thought I found the culprit, but not quite.
I went to browse other photos and found one in particular with a lot of fine detail (hair) and that photo also didn't display all the sharpness that it should have (I was still using software mode). The difference was very slight and to make sure of it it required A/B comparison between Bridge and PS, but there was a difference.
Now I tried the opposite. I went back to hardware rendering mode, restarted, purged the cache, tried again. That second photo looked alright in preview, but the previous photo looked fuzzy again.
So, it doesn't work the same way for each photo...
What's the main difference between the first photo, obviously fuzzy in hardware mode, and the second one, alright in hardware mode but slightly fuzzier in software? The ratio. The first one is a vertical photo, the second one is horizontal (close to square).
I quickly checked other vertical photos and they showed the same behavior...
Now staying in hardware mode, I noticed something else. When I preview the vertical photo and click on it, or double click, it quickly jumps, switching between 2 versions of the photo: the one displayed originally (fuzzy) and another one, with a very slightly different size, which is sharp. During that manipulation it also briefly displays "100%" at the top of the screen. It doesn't stick when you click and immediately switches back, so it looks like a glitch.
Now in software mode, I tried the same, this time you can click once on the photo (which is originally displayed *almost* sharp). When you click once, it displays "100%" but also displays a very slightly smaller version that is clearly fuzzy. Clicking again goes back to the other, less fuzzy one, but doesn't display "100%" this time.
Doing the same test on horizontal photos shows no change that I can see.
So, it seems to me that in the preview mode, Bridge has trouble displaying some photos (vertical ones?) in their actual resolution (100%)
and since there is a slight resizing going on, it brings fuzziness. This doesn't explain the very slight fuzziness seen on horizontal photos in software mode.
Now I'll mention, for those still awake, that I saw no fuzziness on the same vertical photos when I go to Review Mode with *hardware* rendering. Photos there are sharp. Now if I go to the review mode with software rendering enabled, vertical photos are not 100% sharp (akin to the small difference I mentioned earlier while in software mode), while they are sharper in preview.
To sum up, it seems that the only configuration that gives me consistently 100% sharp (=as they were meant to be after post-processing) photos no matter what their orientation, is when I stay in hardware rendering mode and use the Review Mode, instead of preview.
This all really smells like a bug.
For info, I am using Windows 7 and an ATI HD4850 card, and this only about processed JPEG files, not RAW files.
Perhaps the preview is really meant as a quick preview and not a tool to view final photos at 100% accuracy...

How does installation of CC Photoshop and Lightroom affect my current catalogs, previews, and caches?

I am going to subscribe to the Adobe Creative Cloud Photography Plan. How can I preserve (import?) and use my current catalogs, previews, and caches from my current installation of Lightroom? Or will I have to start over once the new version of Lightroom CC is installed?

If you are currently using Lightroom 5 then switching over to the creative cloud is really simple. There are some who say that it isn't necessary to switch to Lightroom downloaded from the creative cloud. But I did. I'm using Windows, so I used the standard uninstall process to uninstall my standalone Lightroom. Then I installed Lightroom from the creative cloud. After the installation was complete there was an icon for Lightroom (just like the previous one because it is the same program) on my desktop. I double clicked on the icon and Lightroom opened the same catalog that I had been using and everything that I had done previously was still in place. You see, the catalog and previews and all those other files are user files generated by Lightroom on your computer. But they aren't part of the Lightroom program. So removing the Lightroom program does nothing to your catalog or previews or preview cache. It's the same program precisely. It's just licensed differently.
If you have been using Lightroom 4 then Lightroom 5 will find the catalog you have been using and will prompt you to allow it to create an updated copy of it that conforms to the new database format. It's no different than upgrading the standalone version. So the short answer is that you shouldn't lose any of your work by switching over.

I have updated my iPhone 3s to the latest software. I had backed up my phone before I did this. Now I have lost my music and apps. I can't sync the phone with my Mac, I can't re-download as the phone says I don't have any music or apps available. Help!

I have updated my iPhone 3Gs to the latest software in an attempt to iron out a problem with a new telephone network provider (Tmobile). I had backed up my phone before I did this. Now I have lost my music and apps. I can't sync the phone with my Mac, I can't re-download from iTunes as the phone says I don't have any music or apps available to re-download although it all shows up on my Mac. The music and app content cannot be restored when I try to restore the phone from the back up I madeon my Mac. Help!

Working on that now. I'm just getting frustrated that everytime I run updates for the phone I end up with tech problems that I have to spend time solving as opposed to updates that actually improve my usage. Now I will once again get to spend hours reloading my phone all for updates that didn't affect my usage in the first place.

You can go strait to SL, all you need is a retail SL DVD available from Apple for $20. The US online store has them at:

I have lost my phone and have no backup. How can I get my pictures back?

Without a backup, you cannot recover data. This is a basic tenet of data.
Did you perhaps have iCloud Photostream enabled?

I have lost my passcode and cant sync my iphone either

PlEaSe HeLp I have lost my passcode and cant sync my my phone either so i cant access anything to change it.

Hi,
I'm not sure if that would work, but just give it a shot.
Don't only hold the home button and the wake/sleep button down till it resets,
try holding it down for about 30-40 seconds.
This time it should not just reset. You just have to make sure it's long enough. You will see ;-)
But then, you will have to put everything back on it again.
Better than having no access, I guess ;-)

I have lost my Iphone and never activated my Icloud on my phone. Is there anyway of locating it whereabouts??? Also Who ever has my phone has downloaded find my phone. Is there anyway Apple can find out the address that was downloaded from??

Unfortuantely, you can only track the phone if you had set up iCloud and enabled Find My iPhone on it before it was lost or stolen. I don't believe there is anything that Apple can do to locate your phone either.

I swapped my iphone from apple store india and my imei of iphone changed and i have lost the box and bill of phone , how can i get my old imei number.

I swapped my iphone from apple store india and my imei of iphone changed and i have lost the box and bill of phone , how can i get my old imei number.

Of course it changed. A phone's IMEI number is unique to each phone. The IMEI number for a phone does not transfer to another phone.
Since your iPhone was exchanged under warranty without having the box and bill for the original purchase, you don't need it now either. The exchange under warranty remains under the warranty for the original purchase.

I have lost the password and the DVD is not working on my old mac G4 500mhz, how can I get back my password?

I have lost my password and the DVD is not working on my old mac desktop G4 500mhz. I have tried use the boot up disk to change the admin password. But the DVD did not work. ( I did not touch this machine for years.) But i need retreive something , so I have tried the shell script in the terminal
1. fsck-y and the mount-uw to try to change and find the service directory's plist to change the password. But after I get the mount -uw, it show illegal option message.
What I can do now to solve this problem? in shell script or any other way?
Thx in advance.

Hi,
A DVD drive that is not working after many years not used:
most probably dust on the little laser lens.
Take the drive out and if you can reach this lens: clean it with pure alcohol on Q-Tip.
Many people throw away cd or dvd players all the time because they stopped working, and very often it can easily be fixed by cleaning this lens.
I used to have a G5, where I couldn't access that lens. It was very sensitive to dust.
I have fixed it several times with compressed air. One time I didn't have canned air, but a bikepump did the trick.
If you have another mac, I'd try to access the G4 internal disk with firewire target disk mode.
good luck

I have lost my username and password and can't find my way to the "firefox window" to see if I can retrieve my sync key.

I have lost my username and password and sync key. I do not understand how to find the "firefox window" described in the "help" page for finding the sync key. I am trying to get my bookmarks downloaded on a new laptop.

Hi Steve,
Depends which OS
version.
If OSX try this instead...
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Change Password from the Installer menu up at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Change Password.*
If worse comes to worse try this...
