747-400 FSX and RadarContact V4.3 Problem II

Hy Simflyers.If i reload a RC saved Flight with the PMDG 747 in FSX SP2, i cant use the Gauges which i select with the Shift+1....9 keys.This Gauges appear for a second wholy black, than nothing happens any time i press the shift+...keys.I saved and reloaded a flight without RC,but with the 747 PMDG Aircraft, all keys are ok.I saved and reloaded a Flight with RC and standard Aircraft, all keys are ok.I dont know is it a RC or a PMDG problem,but together they wont go.This only happens when i reload a flight.Any solutions?I Post this Thread also in the RC Forum.thankshowy1PS: Win XP SP2
