there's 2 different ways to run the program
one adds 2 buttons to your napster program, which allow you to switch servers instead of that one that napster connects you to.
the other way is you run napigator and choose the server you want to connect to, then it will start napster and connect you to that server.
you may have some trouble connecting to some servers because they usually fill up really fast. so just try another server.
hope this helps!
