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.
