IFDG Plane with PIC Panel Issue

Hi Everyone-I'm curious if anyone has had this happen to them or if any advice can be given.I'm using the new IFDG 57's with the PIC Panel. When I lauch FS2K2, I shut down the planes to go through pre-flight and after 5 minutes of sitting on the ground going through pre-flight and loading the FMC, I lose VOR/Radio Frequencies/communication.(I can't hear the ATIS/ATC). I also lose the lights(position,stobes) in the plane as well. Really weird. I'm not sure if this is b/c of the PIC Panel working with IFDG or those planes themselves OR user error.Has this happened to anyone else using these planes with PIC? If so how did you fix? I'd be grateful if you could let me know.Thanks,Brian
