There is no log messages for the crash, I did a complete reinstall of FSX (yes this is the FS9 forum, but since the thread about the aircraft is located here... :( ), SP1 and SP2 today. But with same results

No log message? I had just such a case a few days ago. It was a faulty .bgl file in one of the scenery packages. I would temporarily disable ALL add-on sceneries and try another flight. This way you can at least establish if an add-on scenery is to blame. Good luck!Jure

Philip,I have had crashes with the ERJv2.Approaching KORD fixes in the FMC disappeared .. I selected an approach waypoint and it crashed.So, at that time, I think it had something to do with the FMC .Also, It was with the the original product.Now I am using SP1 and have not done test flights.Are you using ERJv2 SP1 and a "house" livery for testing?After a crash the Windows Event Log will have the module that caused your crash.Go back an scroll through the log, find the reported problem and let us know what it says.
