When this happens it could be a number of things, either you could have a problem with the demo itself where you may not have activated your account or it has run out or it could be a java error. To fix the java error I recommend simply installing the latest version.
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
wont finish the installation process for me i have vista 32bit premium
You probs have Cracked Minecraft. I have the same version, but a server that will work is Serv.MCFaction.net Try that.
What do you mean demo? Runescape is a free game. If you mean member,you can't. If you mean unmember,download jagex. If that doesn't work,i don't know.
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
Maybe your game level is on peaceful or you put torches around it.
you've probably corrupted your minecraft. at the login screen click ''options'' then click on force update. After that you should be fine. Good Luck! :)
They may be outdated, not only the map version but maybe some of the redstone used.
