@ilikeyou: If you are using Windows XP, download the linux chntpw utility from here:
http://home.eunet.no/pnordahl/ntpasswd/
burn the utility into a bootable DVD/CD, enter bios and change the booting sequence to start with DVD/CD drive, load the burned DVD/CD and boot to load the utility. Follow instructions on the prompt. The utility overrides the local admin password and sets a new one, the one you define. You will regain your admin account, and hopefully you can reset permissions on your drive.
If you use the utility wrongly you can damage your system. The last time I used it was on XP, don't know if it works on Windows 7. Good luck
