This might be a warband bug, but From the RGL_Log:
 Unrecognized Module_info directive =  ground_weapon_collision . Skipping.
 Unrecognized Module_info directive =  use_missile_damage_type . Skipping.
 Unrecognized Module_info directive =  hide_other_mod_servers . Skipping.
 Module is not compatible with Warband, module will load all new compatibility resources.
 WARNING: UNABLE TO MAP GAME SCRIPT CODE:  game_get_skill_modifier_for_troop 
BTW that's just the errors i could see, there may be others, can post log.
Edit 1: Hum....apparently i need WSE on my comp, yet i cleanly installed warband and crpg...wtf?
Edit 2:Still get the same stuff even when the  "You don't have WSE" message pops up.
