Yeah Senterpats solution sounds best. The only problem is that i have no idea how GECK works. Ive been trying to understand how to work with it for a while now but scince my moding skill in such programs is minimal i am most likley to mess things up even more than they where from the beginning. Oh and another reason why i use 1.4 for now is becouse of that incorrect version of the DLC error. Some of the Fallout 3 DlC's are completly broken in the way that there are just those error signs instead of items. Ive looked for a solution here but last time i checked it was a problem without a solution for now.
