Not sure if this has anything to do with the disconnecting problem with the new version of lime wire. ( 4.9.30) I was having a problem with this version disconnecting itself after being connected for a bit. I tried the firwall thing then tried opening ports. I have a cable connecting and a router. I turned off me router firewall and enabled windows firewall. This had no affect. I also had AVAST for my virus scanner. When i deleted it and changed to Mcafee virus scanner my disconnecting problems have stopped for now... I have been logged in for 36 hrs and have not lost my connection yet... That I know of..... Hope it helps some people out there since I know it is agrevating to have this problem...
