What IÂ´d try next...I think you need to establish where the problem is:
install the software on another computer (hopefully you have a buddy who will allow this). Try it out....if it works then you are probably looking at something screwed up in your registry, missing drivers or something like that. In this case, you should probably consider re-installing your entire system.
Looking for work-arounds could turn into a giant waste of time.
If the camera turns out to be forked, then you have no choice but to ditch it...from there on itÂ´s easy (and expensive).
ThatÂ´s my 10 cents worth...anyone else?
