Vista - rollback from windows.old

I reinstalled my windows vista home premium 32-bit on my computer but decided to go back to my old installation. I followed the directions at How to restore a computer to a previous Windows installation after you install Windows Vista to restore my old OS, and it seemed to work, but at the logon screen, i ended up with a "The User Profile Service failed the logon" message. When i checked it out, i saw that the users folder had not moved from the windows.old folder so i put the disc back in and tried to move it, but it told me i didn't have access. Right now i'm using the default admin account and the Users folder has a folder labeled Default then AppData, then Local and Roaming. I don't know what i'm supposed to do and i need to get the computer working again soon.
