Hi people!
I had the same problem with HTC Tytn II running on Win Mobile 6.1 and PC on GeoVision 8.2. For some reason Gview V2 stopped working by itself a few days ago. On PC the ports for mobile and default webcam ports were opened and nothing was touched, but the software just stopped responding, and displayed the message "Disconnected" on my PDA. Solved the problem by installing GV 8.3 on PC, and now it works fine, again. I just don't understand how i stopped working in the first place .
