Try removing every single trace of a mod added to TSL and test it to see if it works normally. Then report back here.
Okay, I thought you may have stripped the game of mods by now but you must be away from the computer. Anyways I was going to suggest to you do a basic trial and error of the mods to see which one is causing the issue should the game work fine without them. Also there is a fluke about vista which will I guess partly install the game to another part of the drive meaning that you must also strip that directory of mods. How to get there I don't know but I do know it exists when playing on vista. Sorry I can't help you any further yet but I have to go to bed.
