The exact same thing is happening to me.

1) I checked my java and it's the latest one
2) I tried this
Go to your connections Tab in limewire, if it's not showing up go to Veiw > Show/Hide and make sure the connection tab has a tick next to it...
Then click on the Hosts and remove them and let Limewire search for some more...
It is also wise to go to your Filters, to find this go to Tools > Options > Filters and select the Host Filter and add these IP's into it and select apply...

204.11.219.227
204.11.219.229
204.11.219.231
and that didn't work so I tried
3) I just can't seem to find my .limewire file no matter how hard I search. I am running WinXP

Limewire was working just fine yesterday and now it's just up and decided not to search. Can anyone give me some advice?

Thanks in advance
