I'm having the 'no city interface' problem as well. 2. Windows 2000 Pro 3. FfH2 is installed on F:, otherwise normal directory (all programs are installed on F: ) 4. Store copy of BtS 5. civilizationiv.ini linked below 6. Warlords installed and patched I'm having the exact same python error shown in Psychic_Llamas's image. Edit: I applied the "CvMainInterface.py" file you had in the thread dedicated to the city interface problem, and it's fixed the problem. The city interface is back and there's no python error.
