Do you have the game ini-configured to always load with C2C?Mhm, double clicking a save launches the game loading the mod the save was made with, and then it loads that save for you.
This is as long as the beyond the sword exe is set as the default program for those file formats the saves are in. This should be default when the game is installed for most though.
In my 'standard' Win7 Steam installation, the .CivBeyondSwordSave extension does not have any program to open with defined.
