Hi
i am new to using the CK, but when I try to load up Dawnguard in the CK it crashes the program. I just wish to look for some items and see what enchantments they have on them as I wish to trasnfer them to some new items from a mod I am using. As some of you know some enchantments can not be learnt.

Anyone have a clue as to how to get the CK to work with Dawnguard ?

May also need bAllowMultipleMasterLoads=1
I've done it by just extracting the required strings using BSAopt, I don't know the relative merits of each approach though!
