I can't explain it. the "My Videos" folder in "My Documents" just dissapeared. it is no longer there. all the videos I had are gone as well and they do not turn up in any search. 5 minutes past midnight all was normal then I get some error message on my PC, and when I open my documents forlder it is gone. I am on the verge of tears here. at least 50 Gb worth of movies is just gone. Got McAfee at 100% and no virus that it can see. I even did a system "roll back to 6pm the day before when i know it was still there but still nothing. someone, anyone. PLEASE HELP!!!
