Flew on Thursday and I didn't change anything since last Sunday's flight where everything worked great. I tried the same set-up yesterday and nothing worked. I kept getting a message that said it wasn't reading the vario data and then it couldn't read the GPS. Just locked up. I give up. Back to the old cable, Compaq PDA and Winpilot 13.01.

I'll try the changing the brightness (Backlight) setting, removing/replacing the memory card and removing and replacing Winpilot Pro. Thanks for your suggestions and help.
