GPS -> QPST no longer works after a several uses...

[sdruid]

The QPST program no longer provides 2 ports to add after several uses of the program. I end up having to try a different computer or keep tapping the add port button but nothing.
The computer appears to no be finding the phone when I plug it into the usb port. I heard the connection sound but nothing else, no ports to add...

any ideas..?
