Youtube green screen

[thorgrim29]

Hey, I have a problem with youtube. Since a few days ago it will play sound all right, but all I get is a green screen for image. I redownloaded and einstalled flash about 10 times, doesn't work, tough it did fix a similar problem I had with megavideos. Does anyone have any idea what's up with my computer? I run Windows7 BTW.

This may seem like a silly question, but after re-installing Flash, did you clear your cache and close out your browser before trying to view the videos again?
