Hello,
I bought the vc600 awhile ago and it worked fine with my laptop but when i tryed to switch it to my home computer, there was a big problem, the video window was black, the usb didnt reconize even though i installed the driver, and when i went to the settings, all that showed was this:

Please Help, I Really don't want to replace this and i feel if i do it wont do anything, it seems like a softwear issue.
