I'm an idiot...

Lately I've been playing around with the Command Prompt. I tried out the "cacls" command to get myself access to all folders INCLUDING System Volume Information. A few months after that, my registry got corrupted. THE ENTIRE THING. Safe mode wouldn't even work! I had to do a System Restore.

Now, I have a backup FOLDER with all my stuff in it, but I can't access ANYTHING. I've tried logging in as Administrator. I even get"Access is Denied."
when I try to re-cacls it.

The reason I need help is because I was at the time designing a game... IT TOOK ME FOREVER TO GET AS FAR AS I HAVE IN IT!!! I can't start over because honestly, I forgot the beginning of it. Everyone says I'm screwed..

Please GIVE an answer. This is my last hope..

Specs before System Restore:

Windows XP w/ SP2
Anti-Virus: AVG FREE


Specs after System Restore:

Windows XP w/o SP2
Anti-Virus: Norton Antivirus 2004


My computer NEVER crashes. I just unplug
it..

(Yes this topic is in the Microsoft Windows board b/c I can't decide which it should be in..)Forget it. I'm getting replies in the Microsoft Windows forum.
