Late in responding to the lead question. I did a little research on how to get an FSX plan into P3Dv3 (more like experimentation. When you open the Flight Plan option in P3Dv3, it will give you the normal Create and Edit option tabs; at the bottom is the option to load a flight plan. Navigate to your FSX flight plans and choose one. It should load up into your Flight Plan and then off you go.
