Hi and welcome to flyinside
is your p3d installed in the default location and is flyinside going to that location ? Also is the hdmi plugged directly into your cv1 ? Where are you trying to run p3d from ? It doesn't work from the home store. Can you open other programs ok? Is it a clean install of p3d or do you have addons enabled? Do you see the Flyinside welcome screen ?
