i played a battle of the americas campaign fine, then i got back to the campaign map. then i engaged in another battle but as it was loading it gave me the "sorry medieval 2 total war kingdoms etc etc. has encountered a unspecified error and needs to close"
now i cant even play custom games, quick games, or historical battles. and now it doesnt just happen with the americas game, it does the same thing for the other three as well. my original medieval 2 works fine though.
