Problems with FLASH PLAYER

I know this is an Apple forum but i don't know where else to turn to, as Adobe support won't help at all.

I have an iMac OS X 10.9.2, and Safari 7.0.3

I have latest version of Flash Player (just went through the update).

Now ever site that has Flash shows me the "Module fail" little gray icon.

I can't even watch videos on YouTube !

I've done this :

And also this :

I've uninstalled completely Flash Player, and reinstalled it.

I've cleared everything in Safari.

Still doesn't work.

I've even installed FIREFOX, and this Flash Player still crashes in FireFox !!!

So I KNOW it's an issue with Flash Player... I just can't fix it 😟

Please help !
