HELP!- Crash to desktop.....After a long mission

[Two-Six]

Hi all,
I hope there is a fix for this. I have been out on a long mission into the med and am about 25 saves through the mission, when I try to load up a saved game, I get to the initializing screen, that fades, then the game crashes out with a send an error report message then I get booted out to the desktop.

I have tried loading the last but one mission and the same thing happens.

Can I fix it???

Or do I have to go back to the save in base before mission and start again?

I reeeeaaaaallllly hope I don't have to.
