I used the unpacking softwear in the Medieval II folder so I could unpack my files. But when I did and let it run nothing happened. But now I am only able to play the campaign map & not the actual battles. I have uninstalled the game and reinstalled it but the problem persist. Anyone know what my problem is exactly? I think maybe the registry key that operates the battle system may be corrupted because of the unpacking softwear from SEGA.
