I did eight mission, then I copied all of them to other folder, and I did a mistake - author of missions was DYOM, but I change it to my nick by editing DYOM.dat in notebook.
I just wanna test one of these mission and crash...
Other missions works.
I load mission like this. DYOM > Menu > Mission > Load, Save Mission > Crash
