Whenever im trying to save game in project snowblid - in save rooms, after missions, i press save game and it says "SAVE ERROR", and savegame list keeps beeng blank. help? I already said about system specs somewhere here.
+ I posted it in technical issues forum, but as you said, its not deus ex. and thet there was a forum for this game but deleted. so posting again here. dont like double posting - delete these and move that.
