Minecraft Forums

First of all, hello! I'm new to Minecraft and the forums. After searching online for a solution to my problem and coming up empty handed, I decided to post it here. So when I go to Minecraft's official website and click on "play the demo", I get a "Minecraft has crashed!" window. This happens everytime. I have Java installed and I've disabled AdBlock. I recall accidentally clicking on "Deny" on the digital signature that popped up when I tried playing in browser and now I can't seem to get it to pop up again so I can click "Allow". Could that be it? I'm using a Macbook running Lion.
