Minecraft Forums

Hello everyone.

I have been trying to play minecraft for about 2 days now and it hasn't worked. The first problem I had, was when I clicked "Play", the launcher would exit as usual, but Minecraft (the game) wouldnt start up.

Now, after I deleted my .minecraft folder, I got another error. I don't know what to do, and I really want to play.

Here is the error.
