Nope, no additional modules, got just CIV IV patched to the latest version, got BTS patched to latest version /3.19 I guess/, previous installment od DoC 1.11 went without any issues, I completly erased it from my CIV IV folder, then unpacked v1.12 there, 3000BC works fine, 600 AD and 1700 AD always CTD after the loading screen, I tried that Python exception ... it says "Unidentifiable C++ expetion" error. Sorry, not quite the technical guy am I :]
