iSight camera and Chatroulette

Hi!

I've been having some problems with Flash because my iSight camera doesn't seem to work on Chatroulette.

First of all it should be noted that I read every other thread about the topic and I tried everything suggested: I installed the Beta, checked and erased plug-ins, erased the Safari cache, reinstalled flash, updated my mac, etc. Nothing seems to work.

Also, the iSight does work with Photo Booth, iMovie and so on and it even works with other flash sites like Chatroulette but it doesn't work on Chatroulette.com itself. The website recognizes the webcam (in the panel it is written iSight Camera in the scroll menu, and it's the only camera listed) but I can't send the images and I can't even see the preview in my window.
It has always worked but one day (I don't know why, maybe I changed something by mistake) it just stopped. I could've changed the settings by mistake by putting DENY use of webcam instead of ALLOW in the Flash Menu so I checked all the Flash settings in the global privacy settings panel.

On the panel I changed the setting to "Always Ask" but now when I go to Chatroulette it doesn't work and if I right-click and check the settings the default setting is always "DENY", even if I change it in the panel. I tried many times and everytime I go to Chatroulette default setting is always DENY and if I change it to allow it doesn't work. If I refresh the page the setting is back to "DENY".
Regardless of what I put in the panel settings, I can never get my iSight to work on Chatroulette. As of now, I put on the panel "Always Ask" and when I go to Chatroulette.com and right-click it still has "DENY" checked. If I click "start" and start chatting, the flash window asking me if I allow or deny the use of the camera appears, but if I click ALLOW it doesn't change anything whatsoever.

I don't really know what to do anymore.
