Missions are crashing

[XDragon]

I've been working on a custom campaign and I was going to look at some of the levels for backgrounds I like. Everytime I try to load any mission but my custom ones, the game crashes. All i have installed in the DSUCP. I haven't treid dumping the game, deleting all files and trying it from scratch. That's kind of my last ditch.

Like I said, it only happens when I'm not playing a custom mission...

I have no idea how to fix this. Any help would be great.

UPDATE: I installed everything and went witha fresh dsucp instal. I stuck with the rebel concourse and hanger (much to my dismay) and everything.works again.
