Where have you got the game from? Are you sure you've uninstalled those mods correctly? (if a mod is installed by a setup, it has to be uninstalled by another setup, simply removing some new files will NOT uninstall the mod). I'd recommend a fresh install and a defragmenting run on your HDD. Uninstall the game, keep the savegames, don't revoke the license, delete the game install directory, reinstall the game, update it manually. Take also a look at this
post, it might help you someway. Good luck.
