have you also reloaded the map? (AKA leave and enter again) also what kind of mods did you have? because some mods are purely visual and doesn't affect the game at all, completely safe, meanwhile some mods can be quite destructive.
Ok good, now use it, and then go ingame and switch language to MTL. with all honesty, you can just use ENG... your MTL is probably just way too outdated.
