Windows 7 - Firefox Flash Player Black Screen

I have never had a problem before yesterday with viewing flash videos. Then yesterday, I tried to watch CBS online Criminal Minds and I got audio, but the screen was black and you couldn't access "settings." Then today, I tried to access the viewing feature of documents on Ancestry.com and same problem - black screen instead of a picture.

Attached are pictures of the error logs from the ancestry page.

I have tried EVERYTHING from installing all kinds of different versions of flash player and Firefox and starting Firefox in Safe Mode. I even manually disabled all extensions and add-on's at one point. Nothing works.

I also tried disabling hardware acceleration on Firefox and from Flash player on pages that did work properly. It seems to only be isolated to Firefox, because the Criminal Minds stream and Ancestry docs view fine on Chrome and IE.

Anyone know what those error messages mean and what I can do about them?

Thanks

I don't have a solution, but I do have the same issue. It happens in Chrome too along with Firefox for me. I ran CCleaner to clear out everything that may be causing it, but it still happens. I even Uninstalled Flash with Revo using advanced settings to completely wipe out all traces, but I still get the black box. It's only on certain sites too. Some work some don't. My versions are FF release 10, and Chrome Stable 16.

I spent almost all day working on this and I can't find a solution. Any help would be appreciated. I tried deleting my user profile now and started with a totally clean copy of flash player and Firefox (with no bookmarks, adds ons or anything) and it's still not working properly. Obviously, something is preventing Flash to communicate with Firefox, but I have no idea what it is or how to fix it. Even on the flash player website when it say's if you see an error in the box it's not working properly, I CANT EVEN SEE THE BOX! Anyone?

Just a thought, maybe using their unistaller

Uninstall Flash Player | Windows

reboot, then install flash again, reboot and see if that might work.

Just tried uninstalling with flash uninstall then rebooting then installing again then rebooting again and no change.

I still can't get a fix on this problem. Hoping some new eyes can assist, please^^
