Perpetually Crashing Missions

I've got the US Dreamcatcher original version, with the Gold patch installed. I have a very stable PC, lots of RAM, a fast CPU and stable video and audio drivers.

Since installing the Gold patch, I've replayed the US sub and surface campaigns and the German sub campaign to completion. I'm currently in the midst of the German surface campaign.

The following 2 missions would cause ERT to crash to desktop every time they were played:

US Surface mission #4.

German surface mission #5.

German surface mission #7.

I have no idea why. The crashes never took place at the exact same time or spot.

I've had to bypass the problem by installing a completed campaign file and going back to play the mission following to one that constantly crashed.

Anyone else have similar experiences?

TAG, any ideas what might cause this or how to resolve this?

i was frequently crashing in US missions...but an update of video crad drivers seems to have fixed it...

No. I'm crashing on specific missions. Otherwise, ERT is steady as she goes.

Why not check ur disk to see if its dirty or scratched. The problem might be there.

and if that doesn't work i don't know what to tell you.
