Need help

[catastrophee]

I need to install a P2P program. Ive read the Tuts and when i run click on Apps-Internet- limewire it doesnt load up and nothing happens.

I also need to be able to play games and ive tried installing nvidia drivers and get error's so if i can get some detailed help it would be appreciated!
