Cable connections authenticate on the MAC address of the computer. If you changed computers, the MAC of the network card changed. You'll need to register the new MAC address with your cable ISP for it to work. The easiest way is to use the software setup cd that came with your cable connection, if you don't have that you'll need to call your ISP.

setup cd that came with it did nothing

P.S. You are much better of spending few minutes reading the manul and learning how to configure the Router manaully.

Try this:
Unplug cable modem power. Wait 5 minutes. Plug power back in.
