Crash upon mission exit

[CorwinOfAmber]

Just started yesterday--have played for about a month--Win XP---no system changes software or hardware at all

can load game, play in world view fine, start mission, finish mission---crashed to Desktop with no error message of any kind--just exits program.

Any suggestions?

THanks
