Has anyone got any suggestions on what could be wrong, I can't play any Youtube video's, it was playing them fine on Sunday and now I just get a back square for the Youtube screen.
I can play Dvd's on my pcso it can't be the graphics card. I'm using Firefox but I've tried Opera and Google Chrome.
When I try with and IE 9 it says flash player needs updating but Adobe's website says there isn't an update for a 64bit pc


I can download and view them but I would rather view them online
TIA

Edited
I did some Googling and found another site that had a video and it worked fine so I'm guessing it's a Youtube problem, has anyone else had a problem viewing Youtube vids?
