wouldn't know to be quite honest...since others (birdy and garbagefan2) were helping you last night, I though I'd give a little info as to your ISP (since I'm a SuperMod I can see your IP addy and research it)...

a call to your tech support might be in order....and if you have already installed the new Internet Explorer 7, that perhaps might be the cause...I for one am ignoring said update notification until they get the bugs hammered out of it, so I don't know if there is any effect it has on gnutella clients
