I'm not sure what you mean by "my connection to Limewire itself". Limewire is one of the application packages through which to connect to the Gnutella network. If you mean that Limewire connects to Gnutella and then you have problems while downloading, the advice in my previous post is the correct course of action.

If you mean that there is something wrong with your copy of Limewire so that it is likely to crash (whether on its own or taking the OS with it as well) your only remedy short of switching to Acquisition, is to completely strip all the existing elements of Limewire out of your system using Finder, and then reinstall a newly downloaded version (whether you decide to download the current version or an earlier one is up to you).
