Hi, I am using Vista 64-bit OS. I was being helped by an Electronic Arts service rep when I unintentionally deleted the entire wow6432node under Local System in System. I backed up the registry before deleting anything but I am unable to log onto my account. I turn on my desktop and things load but then the screen becomes black. System restore and using Last Known Good Configuration at the startup haven't worked. I have very important family photos and videos saved so I can't wipe my hard drive before I back those things up but I can't even get to my Desktop. Please assist me in what to do!
