421 Too many connections (1) from this IP

Hello, I'm been have this error for almost a week now..my log is as follows:

[13:36:29] Resolving host name "gametradesg.newsit.es"
[13:36:29] Connecting to 75.126.252.109 Port: 21
[13:36:29] Connected to gametradesg.newsit.es.
[13:36:29] 421 Too many connections (1) from this IP
[13:36:29] Cannot login waiting to retry (30s)...
[13:36:29] Server closed connection

I once left smartFTP to retry 165 times with the same result. To the best of my knowledge, I only have 1 connection to the server. smartFTp is the first thing I run when I turn on my computer and I did not run any other programs simultaneously. I even tried turning off my firewall and anti-virus program to no avail. The first day I started using smartFTP, it worked fine. At that time my firewall and anti-virus was on so I don't think that's the problem. Can anyone help me resolve this? Thanks!

Maybe you have more than one remote window open? Try to close all of them: menu: Window -> Close All.

I tried closing all windows and opening the remote window again but I still get the same result.
