I understand that you are having some issues with connecting your PVX to our test numbers. You mentioned at this point that you are running Windows Vista. What type of processor is running in this PC? What version of PVX are you currently running? If you are running Windows Vista we would recommend the installation of release 8.0.4 on your PC. This may adjust depending on if there is a I series processor in your PC. If that is the case we would recommend installing release 8.0.16 from the link below.
