Well someone already helped you, seems To Dah Window is pretty smart! LOLThe java type doesnt matter. If you have 32bit it should still run. My guess is its a graphics card/launcher. I always get my launcher from a site that does pc game hacking. It's a huge site, I trust it, Been around it a long time, No issues what-so-ever. Mind telling us your GPU/graphics card?
(windows key + r -> type dxdiag and click on video tab and screenie it?)
