Did you grab the latest AmIRC off Aminet?
From my understanding vapor.com doesnt exist or have an IRC server active. A few spots are Freenode, EFNet, and Quakenet. Just depends on what server you want to be on. There are plenty of IRC servers still around.
Just to be safe, are you using Miami or AmiTCP? I only ever tried to use genesis a few times but Miami is still the one I use on the 1200.
Hope it works for you.
