It's not that buggy if you use anti-virus and you know your way around. Come on, I live my live in reality and online. I know my computer inside-and-out. And plus Vista Ultimate, for me, was only $25 bucks so, meh.
Thanks for your help,
Ive sorted it now. It was a problem with the shortcut. I went into the properties in the shortcut, clicked on compatability and clicked "run in 256 colours".
Everything works great now.
