I just upgraded my working installation to V1.0.15 - I did a full reinstall after first having this issue with the Aerosoft Upgrader installation. Both the CRJ 550 and 700 behave the same way - shortly after takeoff (a few seconds), the sim closes. The flights were initiated on the runway, ready for takeoff. Whether I do a complete flight plan, or just kick the tires and light the fires (i.e. set the flaps, take off the brake and advance the throttle to TOGO), I get the same result - CTD shortly after leaving the ground. I removed ALL scenery from the community folder - same result.
Any suggestions on troubleshooting this?
