I don't know why or how, but I bought the game on Wed, May 8, 5:00 PM. This is the same day we got this notice on twitter: "We've temporarily disabled multiplayer for Minecraft Classic while we work on some performance issues. You can still play it as single player! - AP" I believe for some reason the game thinks I did not purchase it when I really did, I do not know what to do I tried to reach by email and waited months but did not get any reply. I am getting tired of it because I can't play actual multiplayer, only singleplayer. I can't join in any servers or it pops up saying "The authentication servers are down" or something like that.
