Start your cRPG launcher, check "repair" and start it. If this doesn´t solve your problem, remove cRPG completely from your harddrive (which means you also have to delete the mount and blade folder in C:\Users\jbratina\Documents) and then reinstall it
I also once had the problem that my game fucked up itself, ladders looked like siege walls, catapults didn´t shoot rocks but tents etc.
Reinstalling it helps there
