3. Go to Common
4. Go to MountBlade Warband
5. Once inside go to Modules
6. Open the Texture folder
7. Find this FONT.DDS (It may take a while to find)
8. DELETE FONT.DDS
9. Start up Mount and Blade warband(If you have Mount and Blade warband already opened Quit out of it to refresh the file)
10. now your mod should be showing text!!!
