Start by shutting down EVE, had too many problems making it play nice, including errors that I couldn't look at to correct, would lock up FO3edit. Next, I've seen somewhere around here that WMKAA12Shotgun.esp also conflicts with some mods - can't remember which, but try shutting that one off for now. If I read to FO3Edit guide book correctly a critical conflict is one that can cause a CTD, a conflict isn't quite as bad - depends on text coloring orange, green, purple, black, good or managable. Red on red - definite CTD (hence critical conflict). I've been going 1 mod at a time trying to updated my bashed patch to take care of any conflicts as they come up. At times it seems like I fix one part of a mod within my patch only two undo it a couple of spaces down.
