SmartFTP Transfering at 0kb/s

Just recently this problem has been randomly occurring and it's extremely frustrating..
While transferring a file over (even a file of 5kb) it just refuses to go, the speed reduces until it hits 0kb/s which clearly will not go anywhere... Now, I hit stop and then go once again, the status then displays connecting and then pre-transfer, then blank.. nothing happens what so ever!

Also I notice that even when it is working fine, the file will not budge until I stop the transfer and hit go again, which then it goes immediately.

Please post the system information from the menu: Help->About "System Information" dialog.
