I downloaded the 4.1.3 beta version of limewire but it still isn't working. I'm a little confused about the last part of your advice. I went into network connections under the control panel and went to advanced and settings and then I added "Limewire.exe" and set the IP address to "localhost" but you still need to fill out the external and internal port numbers. I put 6346 like it says to in the connection problems on the limewire support. Is this what you meant? Does anyone have any ways of fixing this?
