I can not connect
 

I downloaded and was using the Limewire version 3.6.15 and for the last two days I have not been able to log in the program starts up just fine but it will not connect. I use a cable modem that goes through a router in my apartment complex. I am able to connect to the internet but like I said my limewire is not working. I am running it on an imac with OS 10.2. any help will be much appreciated. this all started when I ejected the original driver.
