One or more "nodes" on your network are trying to use the same IP address as your PC with the error message.What in the world does this mean?
Sorry mate, you beat me to it XDthere is another PC using the same IP if you're on static use another number, for ex : 192.168.0.1.
change the last number after 0.
if you're DHCP, try doing a release / renew command
