Ahh. I may just have to "tweak" the mission some more to get it to load. So I can continue on.
Hate doing that though to something someone took the time to create. but if it's the only way.
I'll look for which ships it has in it and try to find out which gives the error.
If I find it I'll post up my findings.
The sim runs fine I can just exit out to the main menu and play another campaign.

Odd for sure.

Thanks for the response.
Now at least I know it could be a ship causing it.
