    I got a message last night, that says "Another computer is using your ip address. Try again later. What does this mean?

    Do you have a wireless router and connect to the internet through that?
    Some one else is using the IP address your Mac usually uses.
    Before I suggest anything, please tell us how you connect to the internet.
    With details, please - OS version, router brand/model, Network Pref pane TCP/IP says Configure using DHCP?

    Forgot to ask you what encryption (security) you have set in the router.
    It does sound like someone is using your internet.
    You should set up the router to use WPA encryption.
    You access your router using a browser and going to or
    You'll need the router manual to know the default username and password for router access.
