I usually dont have any trouble figuring out how to make mods work (usually, just following directions =P) But for some reason, the game freezes on the obsidian slide, with the mods selected. With ttw unselected the game loads as normal. I checked my cache for both games, started over, and then installed ttw.
Okies, after doing some more checking, I attempted to use the program that optimizes the textures, and all of them were not of a recognized file-type. I have no idea what would cause this, but Im going to just shelve it for now, unless in the next little while someone knows where I messed up.
Lol, as a last edit, perhaps it may help someone else, it does it with just fallout3.esm enabled as well.
