Weii.. I've been trying for 2 hours now.
I cant play single player, neither online or offline
I don't haven't brought it - yet.
I can't play multi player,
I've even tried to download torrents with minecraft, neither does that works...

When I try to play the free singleplayer on Minecraft.net there only pop up a window saying: java.lang.IllegalArgumentException: input = = null!
Then I cant do ANYTHING. The whole window freezes...
Same thing on muliplayer...

And, I've tried to download minecraft.exe and reinstalled it 3 times..
(Still, I dont have preminum, but I thougt it was worth a try...)
"User not preminum. Play online once to enable offline."
.. And I cant play online...
I've reinstalled Java and have it fully updated too....

Now please tell what the fu*k is the problem?????
