Using Trend Micro Internet Security Pro....
 

I have contacted my ISP, Trend, and followed all of their suggestions to no avail. Limewire used to work fine for me and nothing has changed on my laptop. Is there a setting within Limewire that may have been changed? I have the firewall message like everyone else...Need some help...

Did you update your Limewire version -- In Limewire Links (below) click on (system details) and fill in as much as you can and post back here

Try turning Trend off momentarily, see if it connects. ;)

Also try deleting your LW Preferences folder whilst LW is closed; instructions here: Point #2 & 3 in Fixes for Limewire (sample image included at bottom of page.)

Some software firewalls you need to remove the old firewall rule and re-add for a new version of LW.
