ok, I just purchased Limewire PRO and I'm not getting any results. I use Insight bb, as my cable company, and even though Insight is blocking P2P sharing I was told that PRO would get around this problem. Another computer in my house also has PRO and has no problem retrieving files. Any help would be useful. Thanks.

I hope it to be true, don't know who told you that. You could try a different port for LW to use. You could try port 80 but in the hope your isp doesn't have a http firewall on it like mine does (don't know if that'd make any diff anyway.)
Go to LW's menu Tools>Options>Advanced>Firewalls & change the listening port to whatever. You could also try something in the 3xxx range or even much larger than 6xxx. If the other LW is working fine then we hope it lasts. Most people generally find LW initially works fine but then suddenly can't even do searches whilst using Insight.
