Flash goes to black on some sites???

This is driving me nuts!!!!!

Flash plays videos in youtube and seems to work for most other apps. But on some sites the video only shows black... the video will never start. (all browsers are affected) (I am using a 64 bit win 7 computer)

For example this site will not play and only shows black:
Armadebtdon 2011 - Call Congress - The Daily Show with Jon Stewart - 07/26/11 - Video Clip | Comedy Central

I have tried uninstalling and re-installing flash, installing 64 bit flash player, have tried uninstalling chrome and re-installing and nothing has worked, have tried terminating my virus and firewall software too.

Try updating your Java Platform as a whole. You may also want to check the browser addons.

Just updated Java and no change.

were you able to view the advertisement?

Advertisements in java or the video page...where?

video plays a 12 second advertisement before the Daily show comes on.

Nope, nothing. But sometimes the wheel spins for half a second then goes to black.

highly recommend uninstalling Java and flash completely: Uninstall Flash Player | Windows

Then restart and install java platform and flash again

Ugh! No change after re-installing flash and Java.

Is there a specific install of Java, and is 64 bit flash required for a 64 bit os?
