I was testing the non-licensed version on windows 8.1 USB capture device was recognized. At a moment I could not record anymore, I thought that was caused by the non-licensed version. I uninstalled the debut software , after a couple of days I bought the software and downloaded it and installed it , registered but now the software will not connect to the capture device, it shows up in the list but I cannot select the input for instance composite. When I tried it everything worked fine. I have tried different USB ports, uninstalled USB device , removed drivers . Reboot and installed everything from the beginning , antivirus unabled and so. It does not work anymore.
