Have a problem with youtube not working. Click on any video and the sound plays but the picture pane is completely blank. It was working ok up until about 2 days ago.
I have tried un-installing flash player and re-installing the latest version and re-booting the machine but that hasn't made any difference.
Tested on firefox, chrome and IE and is the same problem on all browsers.
Other sites like BBC iPlayer, Veoh, dailymotion all work fine. only youtube has the problem.
I have 2 machines connected to the same router and using the same internet connection. Youtube is working ok on the newer windows 7 machine. it is only on the older Win XP machine that it has stopped working.
The problem seems to have started after I ran spybot and Ccleaner and fixed some problems with both but don't know for certain that it was this that caused it.
Please does anyone have any ideas about this problem as I am totally baffled.
