Did you possibly launch the game using one of the other Modswapper options, or possibly not launch the game through Modswapper before loading your saved game? Even if you had launched the game through another Modswapper option or through the normal way without any problem, this does not assure that you will not have some kind of later game problems. Once you launch a saved game in another option, the file will become corrupted, and any future attempts to load that file with the correct option will not solve the problem.
Make sure that the freezeup is not due to the 'Goody Hut' slowdown that is docuemented in the readme (though based on your timeframe, this does not seem to be the case).
