The problem with your bug report can be, that the LimeWire developers aren't able to reproduce the bug. If you can't reproduce a bug it's almost impossible to investigate what's causing it.

So be sure to include your limewire.props file, a detailed description of your problem, maybe even a screenshot and information on which Operating System you are using, what computer you were using, how your network configuration (ie firewall, router) is and maybe even which ISP you subscribed with.

It'd be also helpful if you tried different configurations for LimeWire and your internet connection yourself...
