Have you changed the name of the folder where TATW is installed ( Third_Age_3)? The name of the folder must not have spaces in between: For example, Third_Age_3 is good, Third Age 3 is not good.
If this is not relevant, then you can try few more things before reinstalling TATW:
1. Delete map.rwm file found in ..M2TW\ mods\ Folder where Third Age 3.2 is installed\ data\ world\ maps\ base folder.
2. Go to ..M2TW\ mods\ Folder where Third Age 3.2 is installed \ data\ text folder and delete .strings.bin files :
3. a) just start some campaign in your M2TW with any faction of your choice ( it doesn`t matter which one ),
b) and after that exit M2TW.
If this does not help either, reinstall TATW 3.2 using these steps: http://www.twcenter.net/forums/showt...1#post13170342
