Download bt4 pre final. It is a lot better and has many more improvement. If your are unable or incapable to d/l bt4pf for yourself then you should stop there bc bt4 or any linux distro requires an ability to learn. It is not easy for a noob and if you're just going to ask questions every step of the way then this is not the right forum for you.
Goto the ubuntu forum since bt4pf is based upon ubuntu 8.10. Most questions about anything other than hacking can be answered there.
Also, I recommend that you read the "Idiots Corner" section of this forum to understand what types of things not to say that will get you banned. Too many people are too dumb to read the rules of the forum before they agree to it.
Learn to research on your own. Your qyestions would have already been answered if you searched it first and you would have found out that bt4pf was your better bet than bt3. Stop wasting your time with bt3 unless you have a specific reason for using it, but being that you are a noob then I doubt you do.
