I'm having a problem in the installation process. I get everything going up to the point where it says "installing scripts" and it just stops. I've tryed about 5 times. IDK what the problem is. Any ideas?

Actually it says, "Running Installer Script." D'oh! It looks like people reply to these post about once every 4 months, so I'll just hang tight for some feedback. Thanks.

Hello. I have LIMEWIRE PRO 5.5. It will not connect. I starts fine, buy that is it. All II see is that it is connecting. It doesn't. Can anyone help me?

Try out the MacOSX LW Connection installer found in this thread http://www.gnutellaforums.com/connec...t-connect.html (scroll down to the MacOSX paragraph.)
Also make sure you have added LimeWire as an exception in the MacOSX firewall.

I'm guessing you are not using OSX 10.3 as LW 5.5 will not run on any OSX below 10.5 due to the java versions that were available and compatible for each OSX version.
