I've been a user of mIRC for years, although I haven't done much advanced stuff with it.

Recently- like the last month or so- I'll log in and my favorite channels won't auto-join. I also can't join them manually. I know they are there, I just can't seem to join. Then, if I do manage to get on, I can't DCC anything.

Is this some simple fix that I'm just not getting, or is this some higher level weirdness?
