Suddenly my FMS flight plans can't be saved using the normal SAVE FPL button routine. Does anyone have experience of this and a solution? I've tried highlighting and not highlighting the ICAO plan title that appears with a .rte suffix, but to no avail either way ... And, in case this helps as a point of clarification, departure airfield and destination are indeed different ICAO codes ... Hmmm. :( Advice gratefully received!Thanks in anticipation.David Abrahams

Type OS Vista/W7? Make sure your pmdg directories/subdirectories are assigned admin security rights.
