Access servers using FTP programs like Cyberduck, Coda, etc

Hi there, I posted this question elsewhere, but I'm not sure whether it was the right spot so I thought I'd start a new discussion.

I'm having issues with accessing the server's that my two websites are on.

I've been using Cyberduck for FTP'ing for a while now but this week I bought a new laptop with Mountain Lion on it. One of my websites I use iWeb and the other is through Wordpress, both of which I can access the server (and transfer files) using Cyberduck.

The first time I updated my site it worked. The next day however it didn't - and hasn't since. Now I can't access the server at all. The messages I get, depending on the program, are usually variations on "server not responding" "connection timeout" "connection refused" "connection closed" and on and on it goes.

I have tried using Cyberduck, Coda, Folklift and Transmitter but to no avail.

I tried a little App called 'ftpd-enable' but nothing.

I've tried all the different commands - like the one for Terminal above - nothing.

Rebooted the computer - nothing.

Double checked all the server login details - nothing.

Shouted and screamed - high blood pressure.

I hope someone may be able to help me!

Cheers
