I get the error "Sorry, an error occurred while getting the game instance, Could not open instance file." while trying to open this game. The scenario is Ticinus 218 BC versus pandabianco. The error occurred after I tried to close the game before ending my turn in order to save a local copy in case I got an error uploading it. Apparently the program attempted to upload the game rather than save a copy locally and now I cannot open the game at all and get the error I listed.
