This may sound like a really stupid question (because I haven't seen it anywhere else) but how to you 'backdate' minecraft to an old version to make it compatible? I have 1.9.4 but need 1.6.4 to play crazy craft. If it involves uninstalling and reinstalling mc, that's fine, but how do I stop it automatically updating to 1.9.4 again? please help ![:(]( "Frown :(")
