I'm not quite sure what you are trying to do but it seems you have completely misunderstood how your Limewire software works.
That said, I would suggest that you forget the nonsense you think you know about IP addresses and download a new copy of Limewire Basic and, of course, a new copy of Java V1.5 (aka Java Runtime Environment (JRE) 5.0 Update 12).
Get you new copy of LW from here:
Lime Wire » Official Website & Free Download «
and get your new copy of Java from here:
Java SE Downloads - Previous Release - JDK 5
Good luck.
