Hello.
I have that same kind of issue. Awesomemod opens a window tells me there's a non-core issue with another mod which is not answering the way it should (translated from French by memory, sorry if it's not correct). But, thing is, I tested the game with ONLY the Awesomemod and NO OTHER package - as I had just reinstalled my games - and it says just the same...
If I click "Quit" then it quits after the loading, and if I click "Ignore", it works fine until I try to enter the CAS. When I do, the game crashes.
(I have all extensions up to Master Suite Stuff)
