Flash player not working on certain websites. Help?

[Ahrcsnave]

Ok, so my flash player works for just about every site, with the exception of two so far: the Cosmos website and the Zero Punctuation website. The videos there just appear black. The player works everywhere else I've tried.

I'm currently using Chrome on Windows 7 and this problem only just popped up this week.

Any help would be much appreciated!
