I'll try reinstalling windows. Yes i've tried closing everything down. The difference in our versions, is my bro is using 6.0, and im using 6.0.1, but i had 6.0 and it didnt work. I had it on another machine, with a different card, and it doesnt render there, i'll try take the file to school with me and im sure it will render on those computers, i just dont know what the hell is wrong with it =\.
