Can't connect?

[hammysandwhich]

Alright guys, I'm having problems getting onto opticraft.  For some reason it keeps telling me:

Failed to connect to the server

Connection refused: connect

This is really annoying me, I have had problems all day and its annoying as!  I have re downloaded the minecraft.exe I deleted it and then re-installed it, I have completely gotten ridden of my .minecraft file in the %appdata% file.  Any help would be appreciated.

Also I have tried logging onto opticraft with multiple laptops.

And when I try logging in

That's exactly the same with me sonic.

Please help us...

Also for those wondering I have had lots of problems trying to log on today, a black screen, minecraft not connecting to minecraft.net, making me have to play offline.  Stuff like that =p
