I replaced all of the base files (base.rte, ronin.rte, undead.rte, etc) and it still gives me this error.

I checked the mod manager and everything is enabled.

Using Vista? Have your game in Program Files?

I've been using CC for a while. Just last night I played for 1 or 2 hours.

I'm using XP, I haven't messed with the files in a few weeks except adding 1 or 2 mods.

So I can't imagine why it suddenly decides to mess up.

Check abortscreen.bmp to find out which module caused crash and then tell us which or remove it if it is a mod.

I say it was 100% vanilla because I reinstalled CC to another directory, deleted the vanilla folders in my existing CC folder, and replaced them with the alternate download files.

Here's the problem I guess...oh ♥♥♥♥!

Sorry, I hadn't looked at the abortscreen yet. Apparently it's Boba_fett's mod that's giving me problems and referencing Coalition.rte incorrectly. Coalition.rte has no problems, it's DEF.rte that's the problem.

Oh well, problem solved.
