Do you have your OSX firewall active? See issues about firewalls involving OSX firewall & also modem/router firewalls here Connection problems? Check here first! (click on link)

Also if you're using OSX 10.4 then you should make sure you're using Java 1.5; see Setting up Java 1.5

Thanks.
I am using a firewall. And i have tried all the connection tips. The weird thing is that when it doesnt give me an error message, limewire works fine. I am currently updating to java 1.5 so maybe that will solve the problem. Limewire freezing up isnt that bad, the problem is it forgets what song i have downloaded and what songs i am currently "trying" to download. its really annoying becuase i end up downloading the same song twice. i say that because with my slow dialup i get only a couple song a day!
Hopefully, issue is resolved.
