I have bought CIV IV complete and that gives three programs to start CIV IV Complete, CIV IV BTS and CIV IV Warlords. Since BTS is the last one, that is the one I want to play. Of the three the two others start fine, but BTS crashes on load. First I get a message that Windows has to change color scheme (does not get that with the two others), then there is the normal CIV IV load box for a while and then I get "CIV IV is not responding". This in on a Windows 7 64 bit laptop (ASUS G73JW). I have tried "Run as administrator", I have tried Windows XP compability mode, I have tried all other settings I could find under properties for the exe file.
