I just re-aquired this game (it was a favorite game of mine long ago) and now I have a problem with the scenario editor that I can´t solve on my own. When I load a map from a savegame in the editor, it crashes whiles saying that I have too little virtual memory and that I should make sure that I have at least 128 MB of virual memory. (When making my own map in the editor, it seems to work fine.) Now, I run the "sold out" edition of Alpha Centauri and Alien Crossfire. My system is Windows 7 64 bit, 8 GB ram (and windows standard virtual memory). I have tried both with the windows compability patch and without it. I have tried running the game in compability mode for Windows XP. I also uninstalled the game and reinstalled it on the system drive, but so far nothing helps. Does anyone have an idea what to do to make it work?
