hi i have just bought a 12inch apple g4 powerbook its brand new and i downloaded the newest limewire 3.8.7 and when i start a download it just stays on the 0kb speed and the progress bar comes up and just sits at zero . i have left it on for a long time about an hour but it will still not move. i am a girl and i dont know much so any help would be great! PS i have a 56 k internal modem
