I just downloaded Mountain lion and its deleted EVERYTHING! How can i get it back??

I just downloaded Mountain lion for my mac book pro, and now it has deleted everything on here. Its my school laptop and i will be killed if i can't fix it!!! Can anyone help me get all my memory back??

Restore the system from your Time Machine Backup.
Just downloading and Installing OS X Mountain Lion does not Delete anythng. That is a User choice and not really even a choice during the normal install of Mt Lion.
So it was Not Mt Lion that Deleted everything, that was you that made that choice during the install.
Maybe you shouldn't of made those choices with a computer you needed to use for school.

I just updated my iphone, and i lost everything. how do i get it back.

how can i resore the things i have bought to my computer. My computer had to get a new hard drive, but i still want to have the things i have bought back.

Try going to file-devices-restore from backup, if you dont have a backup then you may redownload past purchases (movies, music, apps, etc) from their respective stores by visiting "purchased" section.

Eli,
You can reset a Password (lost/forgotten) set on your Mac using 'Reset Password Utility' available with OS X Utilities tool. With OS X Mountain Lion, OS X Utilities tool can be generally found on a local hidden Recovery HD Partition if your Mac has one.
To check If your Mac has got a local hidden Recovery HD Partition, start your Mac holding COMMAND + R buttons. If you hold the keys pressed enough and there is a local Recovery HD Partition on your Mac, you will be presented with OS X Utilities window.
Click the 'Tool' menu item and choose 'Reset password'. Terminal window appears. Type 'resetpassword' into it and press 'Enter'. Reset Password window appears with User Account Names available on your Start-up Volume. Select the User Account Name and rest is simple to follow.
One of the advantages of this method is that it does not require any Authorization method such as administrative authentication to reset a password.
NOTE: If your Mac does not have a local hidden Recovery Partition on its system disk, you can create one using Disk Assistant application available from Apple. Search for the Disk Assistant in the support area.

Try deleting the cache associated with the App Store.
Quit the App Store if it's open.
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type this exactly as you see it here:
~/Library/Caches/com.apple.appstore/Cache.db
Click Go
Move the Cache.db file to the Trash.
Launch the App Store. See if that made a difference...

I just have just downloaded Mountain lion and I wanted to listen to music on my computer screen with my HDMI cable plug into my back of my screen and I wanted to talk to dictation on my regular standard iPhone headphone and I was wondering if it's all possible change your settings Mac Mini to set it so you can listen to those both like your headphones and use the mic in your headphones and there's no settings that would change in the Mac Mini so do there is a flaw in this system or I am just really really really really dumb.

You computer is probably perfectly repairable, but if you want a new one anyway, it is perfectly possible to transfer the data from the faulty one.
But it would be a mistake to simply put the old HD in the new computer.
These are the steps:
Remove Hard drive from faulty computer. (very easy on Unibody MBPs, do-able but not so easy on older MBPs)
Put it in a cheap enclosure
Connect it the new computer
Boot up new computer.
If the new computer has never been run before the Setup Assistant will ask if you want to import your apps, data, settings etc from either another mac, another HD connected to the Mac or a Time Machine back up.
Obviously chose the second option (another HD connected to this Mac) and follow prompts.
If the new computer has already been run (so Setup Assistant doesn't run when you boot it up), you will need to use Migration Assistant...or run the installer again so that Setup Assistant runs again.

I just downloaded mountain lion and now my google chrome and spotify wont open

I just downloaded mountain lion and now my google chrome and spotify wont open. Any help would be appreciated.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

I've just found the keyboard shortcut in Garageband for 'copy region' had changed from cmdC to ctrlC. I went to Preferences and clicked Restore Defaults for shortcuts. Now its altC . How can I get it back to the original commands.

When I use find file http://www.macupdate.com/app/mac/30073/find-file (which does tend to find files that "Finder" can't), it's not coming up with any other itunes library files that have been modified in the past week, which I know it would have been - unfortunately, I don't have a very recent backup of the hard drive. It would be a few months old so it wouldn't have the complete library on it....any ideas? I'm wondering if restarting the computer might help but have been afraid to do so in case it would make it harder to recover anything...I was looking at this thread https://discussions.apple.com/thread/4211589?start=0&tstart=0 in the hopes that it might have a helpful suggestion but it's definitely a different scenario.

If you are running Lion then all drivers are distributed through Software Update. You do not need to install anything, other than to install the printer in System Preferences > Print & Scan. If you already added the printer while it was connected using USB, you might want to delete it and set it up again wirelessly to avoid confusion. Or, give them two distinct names e.g. "Photosmart D110 (USB)" and "Photosmart D110 (wireless)".
All scanning functions are now performed using Preview, but you can also access the scanner through the same Print & Scan preference pane, or with Image Capture.
This HP document may help explain how driver software is distributed now:

As far as I know rentals are one-off downlaods, but you can try contacting iTunes support and see if they will grant you a re-download : http://www.apple.com/support/itunes/contact/ - click on Express Lane, then iTunes > iTunes Store

Your notes should be stored in your backup, so if you have backed up the iPad and that backup does contain those notes that you deleted, you can try restoring from your backup. If you haven't backed up the iPad since you created those notes, they are gone.
If you backup with iCloud only, restoring from backup involves erasing the device and then going through the setup all over again and finally restoring from the iCloud backup. This article explains the process quite clearly.
http://gigaom.com/apple/ios-101-set-up-and-restore-from-icloud-backup/
If you backup with iTunes, connect the iPad to your computer, launch iTunes and right click on the device name on the left and select - Restore from Backup. But before you do that .... turn off auto sync in iTunes - without connecting the iPad - launch iTunes and go to Edit>Preferences>Devices and check the box at the bottom of that window in order to turn off auto sync.
Email messages are not stored in your backups.

I recently reset my computer to factory settings. I re-downloaded iTunes, but lost most of my music and all of my playlists in both iTunes and my 4S. How can I get this back?

Restore your media from the backup of the computer created prior to restoring the computer.
You did create a backup, correct? Not doing so would be extremely unintelligent.
iOS devices are NOT backup devices.

Oh!
First thing I think would be to do a search for the folder in case it's somehow got moved.
Failing that, you can retrieve the folder from your original installer disc using Pacifist.
Insert the disc (don't boot from it) and open the installer package with Pacifist. Navigate to the Desktop Pictures folder (might be a bit more fiddly to find in the package structure). When you find it, select the folder, right-click (or ctrl-click) and select 'install in default location' from the context menu.
Exit Pacifist and eject the disc.
Best of luck!
