nevermind guys, i continued the research on the forum and found the following solution:
- simply move your save games (*.SAV files) to any other newly-created folder of your choice & diplomacy will work again
What was the full address path for your saved game? For example, "C:\Games\MPS\CIV2\FileName.sav". Did it happen to contain any unusual characters, full stops/periods?if someone could help me on this one it'd be really cool!
