Well I have the same issue… I did just the above including going out and buying a new web cam. But that didn’t seem to fix the problem either. So I finally gave up and tried this to see if it changed… I made a new screen name and believe it not it works.. only on the new screen name.. not the old one… so when I feel in the mood to have lots of people on cam I change names. I dont now how to fix the problem on the other screen name but anyway try a new screen name and see if that works.
