I know of some who have had this problem with Total War. The SS uninstaller seems to garble things up sometimes. It's recommended to use some 3rd party uninstaller, e.g. "Total Uninstall", "Uninstall Manager", "Uninstall Plus", "Ashampoo Magical UnInstall" or some other uninstaller (these are to be found at download.com and other such sites)...along with some registry cleaner, to clean out Total War and all the mods.
