Problems with reinstall

[Taserpenguin]

I reinstalled my Fallout goty to try and get FOSE to work. It still doesn't, but now whenever I try to start the game, something causes the game to crash. It is also in a windowed state for some reason.

My load list is as follows:

fallout3.esm

anchorage.esm

thepitt.esm

brokensteel.esm

pointlookout.esm

zeta.esm

CRAFT-activationperk.esp

CRAFT.esm

xcalibruniverse.esm

xcalibruniverse.esp

xcalibruniverse_ammolists.esp

xcalibruniverse_repairlists.esp

fellout-full.esp

Any help would be appreciated
