@lymond, if you are having interface problems, you may be getting python errors. Try turning on logging in the CivilizationIV.ini file. There is one for each expansion in it's folder under My Games.
You can post the Python*.log files here. They are found in a Logs folder in the same folder as the ini file.
Code:
; Enable the logging system
LoggingEnabled = 1
; Overwrite old network and message logs
OverwriteLogs = 1
