Flash player detected as installed but not playing movies

Hi,

I've been struggling with that problem since a yesterday. I do not know what is my next move, so I'm seeking help here.

Problem:

Since a couple of month, everytime there was a firefox or a flash player update, the flash player was not working anymore within firefox. Usually, turning the addon off and back on was working and life goes on.

Not since yesterday (may 28, 2013). There was a firefox update (v 21.0) and now I can't make it work anymore.

For example, when I go on youtube, the screen stays blank. Nothing happens.

If I go on grooveshark.com, after a couple of seconds, I have the folliowing warning: "We had a problem loading Adobe Flash. You may have a Flash blocker installed.  If so, please disable the blocker (or add an exception) and reload to start listening." I have no 'blocker' (although I do not really know what they are referring to).

My system:
Windows7 Enterprise 64b

12g ram

firefox21.0

Here's what I tried (in no particular order since I do not remember all I did... ):

1. Do I have the latest flash installed?
http://www.adobe.com/software/flash/about/
Yes. 11.7.700.202 at the moment.

2. Is it working fine?
http://helpx.adobe.com/flash-player/kb/find-version-flash-player.html
I do not see the movie, but I see the flash/os/browser version in step 2.

3. Uninstall flash

4. Resinstall latest flash

http://get2.adobe.com/flashplayer/

5. Try firefox in safe mode

http://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using- safe-mode

6. uninstall flash (again) uninstall firefox

7. reinstall firefox 21

http://www.mozilla.org/en-US/firefox/new/

8. reinstall flash

http://get2.adobe.com/flashplayer/

9.  Try firefox in safe AND with a new profile

http://forums.adobe.com/thread/1018071

10. Tried Process monitor to figure out what was the problem. Inconclusive for me.

I have the log file, but I can't find how to attach a file on the forum. Maybe I can send  it by mail to someone?

It always ends up with the following:

There is no action between the Thread create and thread exit? That seems weird to me.

Todo:

11. debug with WinDbg (but I'd rather not get there since I'm not very sed to WinDbg)

Some things I noticed:

When I kill the flash process withinin the task manager, firefox detects it as if it has crash and display the problem error message.

It works fine in IE8 and Chrome

Does anyone has a clue on how to help me?

Thank you.

Also, here's the two last entry in my FlashInstall.log file:
