make sure that you have all of your settings configured correctly. Make sure that the IP Address is correct. Also, you may want to go into settings on UnleashX, and look to see if it has FTP disabled. Also, UnleashX, may have a username and password for you to use with FTP. You could probably find that in the settings section on UnleashX.
