I'm having the same problem too. I installed Limewire 4.14.8 and it worked fine for several hours. I left my computer then when I got back, all downloads has stopped and I kept getting the same message (Connecting, Host Tried, Need More Sources) when I retried. Limewire can still search and upload, but seems like it can't download. I have another PC with Limewire 4.12, and it works normally. Maybe some bug in 4.14.8?
