Thanks for the reply, I tried saving in my documents, it didn't make a difference. I don't think it's admin rights because it wouldn't have saved at all. I Also read somewhere that because this engine is 32bit it can't ever read more than 3.5gb of my RAM so my whole pc upgrade was pointless . This engine seriously needs some work if it wants to stay alive. It only uses one core and doesn't see more than 3GB RAM, although I am to blame as well, all my buildings and roads are blocks not models, maybe if I convert sections of my map into models or separate map entities it might require less RAM and make the .wmp smaller?
