Okay, I'd like to start off by saying I'm kind of new to this whole server thing - but I've been able to play Minecraft on my friend's server for several weeks without a problem, using update 1.6.4 (since that was the only one that worked). Suddenly though, it keeps saying Connection Refused: Connect. How do I fix this?
Added (1). I have restarted minecraft multiple times and i don't know how to join another server. I only have the one server
