I'm sorta having the same problems but it's weird. I've got Windows on my computer and when you sign in there's mine,which is the administrator, and my boyfriends. When we downloaded version4.18.3 his started messing up but everything on my side downloads. i've tried uninstallingit from the whole computer and reinstalling it and we have the same problem. My side is up and running and can connnect but when we log onto his side of the computer it only has the first bar and won't go up. we've connected and disconnected a couple times and still nothing. There is no firewall blocking it but it has the symbol saying it does but then again that's been like that since we've started using LW. Once or twice when this first started happening I would get on internet explorer to sign in here and then check his limewire and it would be connected but it doesn't always work and I don't know how to fix it. I will try looking at other posts but i'm not that computer literate and I don't know what this problem would be under. Thanks for any help and i'm sorry if this post is a little confusing.
