No I can't. I deinstalled and reinstalled Plan-G and run it as an Admin. There is no question to built a new DB. I have only the information- and flightplan-window nothing else, so there is also no possibility to rebuilt a new DB.

Yes I confirm, I have only PlanG3_FSX, PlanG3_FS9, PlanG_XPX, UserWpts3 and MEF in C:\Users\Carlos\Documents\Plan-G Files\Data

Hey at all. My Problem, since two days, the main window don't open, I have only the Information- and Flightplan-Window. I don't know why. No errror-messages, nothing. Any ideas? Thx Carl8
I work with P3D. In the log is the following message:
