I can't watch videos i've downloaded from Youtube.I could before but now.I can hear the sound from the videos but can't see anything.Also this began after i accidentally made Real player as run as administrator.So i'm wondering if that's the problem and if so i'm wondering if i can not have Real Player run as administrator.

Did you try undoing what you did? Always pop back and let us know the outcome - thanks
Given RealPlayer's history, IMHO, I'd advise removing it entirely... http://en.wikipedia.org/wiki/RealPl...
