I'm also unable to connect to limewire... I connected fine before the Thanksgiving holidays (to 16) and have been unable to connect since... I dowloaded 18c and not only can I not connect but when I click connect it won't even attempt to establish a connection. Also, were the community tab, the"connect" button, the list of discovered hosts and autoconnect hosts under the connections tab supposed to be missing from the 18c interface?

Thanks for your help and I hope this can be fixed. Limewire is a great program.
