you have an opengL error which usually means you have to update your graphics card drivers.

which graphic card do you have?

was the demo play ever working or was this first time you tried it?

Nope, I played this Demo a couple of months, but it does'nt need any Java or any requirements that I need.It's just I was looking for a cracked server, after I installed the cracked Minecraft, I accidentaly installed Java7 Update 55 and then the cracked Minecraft, you press the Play, it does'nt let me play even the Demo.But this problem only started when I installed and uninstalled Java.
