Can i downgrade form 10.8.2 to 10.8 with out loosing data?

I recently got a new macbook bro and logic pro and i have a M-Audio profire 2626. Apparently M-Audio has not made a driver update that will work with 10.8.2. Its it possible to downgrade to 10.8 since that is the most recent os that will work with m-audio. Also, will i loose all my data if i can do so? Any help would be much appreciated. Thanks

Where would the OP get this original ML 10.8.0 installer from?
Unless you meant the OP made/kept a copy of the installer from the recovery partition.. and as the recovery partition gets updated to the latest OS version prior to it being sold (or as soon as you update anything) and the OP said he just got a new MBP I would imagine it came with 10.8.2 preinstalled so the OP won't have any means of getting 10.8.0 anyhow...
I'm also not sure that running the installer and re-installing 10.8.0 over the top of 10.8.2 would work anyhow.... I think one would have to erase the HD and then reinstall to get a successful 10.8.0 roll back..
a) Talking in general for a moment, rather than for this specific OP and Mac, you had replied that it was not "easy or practical to downgrade to v10.8.0".
It is NOT sufficient to simply work from the Recovery partition, which will be "up to date".
If however, you make a copy of the OS installer application as soon as you download it, or possibly make an installer USB key or a DVD from it, it absolutely is (again, generally) possible to downgrade an OS from, for example, OSX 10.7.4, to OSX 10.7.0. (or similarly with Mountain Lion) without the need for a disk erase.
I just carried out the process before I posted. With some forethought, or resourcefuness, it is "easy and practical", if slightly time-consuming.
Perhaps this will help to convince?

I suggest that you give it a try.
As I posted earlier, it is NOT possible to 'roll back' to a completely different OS (M Lion back to Lion for example) this way. One would need to wipe and re-install.
b) Returning to the OP's specific situation:
I also posted that there might be issues with a new Mac not being compatible with an earlier M Lion version.
It may well depend on the specific version that the new Mac came installed with, and i) will the Mac actually run with an earlier OS, and ii) if the OP has access to a copy of the original (earlier) OS.
I do have a fairly recent MBP that shipped with M Lion, but do not have the time to actually try rolling back it's OS to v10.8.0 to test if it will run.
It may not, of course, solve any of the primary issues for the OP and MAudio kit, as has already been pointed out.

Hey floridiansue,
Do you have an installed email program such as Microsoft Outlook? If your email is through an online login, such as Gmail, etc, then one will have to create an email association with a program such as Microsoft Outlook on the PC for this Scan to Email system to function.

Bought a new Mac and iTunes won't let me sync new music to my phone because I used to sync it in my old Mac. How can I sync with the new PC with out loosing the music I already have in my phone?

Copy everything from your old computer to your new one then sync.
Iphone will sync with one library/computer at a time. Syncing to another will indeed erase the current content.

Please help!

Was your iPod previously set up to Manually Manage (where you dragged/dropped the music) or was it set to auto sync (where it started sycning as soon as you plugged it in.)?
If it was set to Manual, you have no worries. Just continue on your way.
If it was set to Auto, you will have to transfer your purchases or redownload them from the iTunes store.
You're either going to have to get the other music back from the websites/CDs you got them from before or find an iPod ripping software program that will do it for you.

Can I delete my icloud back ups with out loosing my current data on my iphone 5

Hey guys. I was wondering if I can delete my iCloud backup with out loosing my current data on my iphone 5? I can not up date my phone because it says I do not have enough storage available. Yes, I have purchased more storage space on iCloud.
Thank you!

Yes you could delete backups without loosing anything on your device, but iCloud storage has nothing to do with your local device capacity. I guess that your device is just full and that you have to delete something like apps, movies etc to free up some space for other content.
iCloud uses its storage only for
Photos and videos in the Camera Roll
Device settings (for example: Phone Favorites, Wallpaper, and Mail, Contacts, Calendar accounts)
App data
Home screen and app organization
Messages (iMessage, SMS, and MMS)
Ringtones
Visual Voicemails
purchases of apps, music, videos do not count against your iCloud storage capacity ( but please see also iCloud backup and restore overview http://support.apple.com/kb/ht4859).

OK, so I went and explored what this site said about Mackeeper. But before I delete it can you tell me:
If we don't need anti virus program and if the one that came with the machine is supposed to do the job then what does that say about the viruses that Mackeeper says it found? Were they not there and the program made them up? Or were they there and Apple didn't deal with them?
Thanks for all feedback.
They were not there and MacKeeper made them up. Delete it completely. I have seen it cripple people's Macs.
Uninstall MacKeeper

Please someone help me?!

You have to connect the iPod to your syncing computer and restore via iTunes. If iTune asks for the passcode and yu can't enter the pascode or if you do no have the syncing computer you hove to place the iPod in recovery mde and then restore.
If you did not previouly sync to the computer after changing the passcode, iTunes will ask for the passcode. Placing the iPod in recovry mode will erase the iPod. That is the way this security feature works.
You can restore from backup but you will lose everything since the backup.

If you have not had a backup of the data before, you need to check this support document you linked here from about removing the passcode. Without a current backup, you are going to lose data.

I have applied the icloud on my sisters id accidently. How can I no w remove this information and set up my own Icloud on another computer with out loosing either of our information from the phone.

Please read before going through with this procedure.
If you really want your contact back and you did not do another iCloud backap since you deleted some of your contacts, you can do a hard reboot on both devices with iClouded contacts by holding down the home and lock buttons on each of them for 10 seconds ignoring the slide to turn off thing. Make sure you have iCloud contact services off before doing so. You can then go through the whole set up process until you get up to the backup part. You then press to restore from an iCloud backup (make sure you choose the right backup for the right phone). If you didn't make an iCloud backup before the contact incident, you will have to use your two-month-old iTunes backups. Each phone should have their contacts the way they were from your last backup. You then go into Settings>iCloud>and turn off contacts. You then can choose if you want to keep your current contacts or not. Turn this off on both phones just incase you add another iCloud device to the mix later on. Now your contact lists are no longer linked (Caution: side effect may include lack of edit button). You may now add and delete contacts as you please without it happening on your other phone.
Thank you for choosing Apple.
