Hi mlledes!
I think I know what your problem is.
LimeWire 1.6x is notorious for gnet connection problems and incoming port # errors. These errors were, for the most part, the result of java 1.1 vs 1.3.1 Java Run Time Enviroment conflicts within the LimeWire software. There was a link to a temporary patched version, but this has since been taken down (Version 1.6 is a bit old). If you don't mind downloading a newer version, the problem has been fixed in 1.7 and above. I recommend LimeWire 1.7c. It doesn't have any ads or spyware, like 1.8 and 1.9 do (please, no flaming here about this - start a new thread if you want to). Here's the link:
