Re instull Minecraft
They don't.
it might be your visa card try email visa and/or minecraft for suport.
it should work fine unless u have a crash
It works fine on a vanilla version (no mods) so it probably means you have a mod for it so you will have to wait for the maker of the mod to update it to the latest version.
No, it won't. You must have the correct version of the mod to go with a certain Minecraft version. Id est. Mod for 1.8.1 would only work with Minecraft 1.8.1 and possibly 1.8, but it may not.
You probs have Cracked Minecraft. I have the same version, but a server that will work is Serv.MCFaction.net Try that.
only minecraft classic multiplayer is free, beta mp is for premium only a.k.a buy the game.
Not if he keeps playing minecraft in miss andrews' class he wont
