When flying the 1st tutorial flight for the PMDG 737ngx (using the FS2Crew addon) the system crashes a few minutes after take Off. The error msg simply says "MSF has stopped working" and they will search from problem solution. This problem occurs at 2.6 nm short of the Detling VOR (DET) along the route EGKK-EHAM. I would appreciate any suggestions on how to fix this problem. Thanks!
