Using Omegle and ManyCam

I tried using ManyCam within Omegle recently after purchasing a new Macbook Pro. When in Omegle, I cant seem to get my flash player to recognize Manycam as a video source. The only option I have is the default, which is listed as USB Video Class Video. I know i've used this program this way before, but for some reason it wont recognize it. I've tried installing and uninstalling everything (manycam, flash player) several times over and have used different browsers as well, all to no avail.

Ideas?
