I have a problem with video calling. I can see other person, they can see me - but I cannot see me.

Everything seems to be in order - I even called in a computer company to test my equipment out, but they say everything is in order and possibly is a problem with the new Skype version.

I have Directx9c and more than adequate GHz. The only thing wrong is no video of me. My webcam is Trust 15007. Does anyone else have the same problem or can anyone give suggestions.
