ok, somebody's gotta know

i got good news and bad news. good news is, i now, technically, have high speed internet service. bad news is its aol, through my brother's dsl modem and router (i got to make a hole in the wall!), and i can't make anything outside of aol work. no netscape, no kazaa, nothing. its hardly worth it. and for the life of me, i can't figure out how to fix it. i've been futzing with it for like five hours to no avail... its so frustrating! at least i'll be able to use it to buy concert tickets and whatnot, but what i really wanted it for is downloading crap off the internet, and that's very difficult when i can't connect to kazaa. blah. so anyone have a clue how to fix this?
