well, tried making a new account to see if that would let me in but no change, it keeps insisting that the domain, which is the same name as my pc, is not available. I changed the computer name a couple of times and each time the name of the domain changes. Well, at least I could get into safe mode and back everything up so I can format it tomorrow. Maybe I need to buy better antivirus than keep relying on AVG and Spycatcher. Sometimes you do get what you pay for.
