Hi Bill,
I don't know the VS-Software yet, because I never installed it. I used Sonar 8 or 8.5 when I bought my VS-100.
But is it possible to start the VS-Software without connecting the VS-100? Maybe then it's possible to change some settings or to use the internal soundcard? Or run the VS-Software as an Administrator? Or what happened if you uninstall the driver of the VS-100? Maybe this is the solution. Not uninstalling the software but the driver. After uninstalling run the VS-Software and try to change some settings. After that, install the VS-100 again.
You have to try everything what's coming up!
