Hi,
I'm having exactly the same problem. Also with the new update as well (1.0.7). I bought it couple of weeks ago via marketplace and have always had this wasm crash. Its always when I try to create a custom waypont (like a ETOPS ETP fix). I have no other WASM problems and have flown a number of flights with no problem. It happens 100% of the times if I create a custom waypoint.
Thanks for your help!
Pedro Grancha.
