Ploesti Mission

[GS123]

I get to within about 15 miles of the oil tanks when the message "You have performed an illegal operation, program will be shut down." I've closed all running programs, i.e. anti virus etc. but to no avail. Has anyone else had this problem? Any suggestions to fixes???

Is this Bill Potvin's Ploesti? If so it's one of the oldest 3rd party missions for CFS1 & created by a real expert & pioneer. I'm sure there's no bugs in the mission itself. I no longer have CFS1 installed so can't check it out. Make sure you followed the instructions & installed everything properly. It sounds to me that a 3rd party mission object is missing.
