Milne Bay campaign crashes to desktop.

Just finished loading this potentially great campaign, which was a challenge with all the add ons but it looks great and I can't wait to get stuck into it but for some reson every now and then when running it the whole of CFS2 just crashes to desktop. My pc is still running fine and all I do is restart CFS2 .
Has anyone else had this problem.
My pc should be fine as I had just rebuilt it with new parts and this campaign was put on a third cfs2 install with DOA Australia campaign which runs fine and is stable.
(ps - Dual SATA 10,000rpm Raptor drives on Raid 1 Stripe make this game fly!!-- I can;t believe the speed !)
thanks
