I would higly recommend reinstalling the game but to be safe, try deleteing the CRPG files form your modules then reinstalling them back. If that fails then reinstall Mount and Blade.
After doing all of that try your best to figure out what kind of graphics card you have, what kind of internal computer parts you have (Ex. Nvidia or AMD/ ATi) Once you do go to the ATi or Nvidia website and go to drivers and it should automatically check your computer and see what graphics card you have and type of OS. Then go through the steps and download the recent driver updates.
