Bought to tunnel VNC over SSH but doesnt work

Attempting to tunnel VNC over SSH does not work. Just get a connecting... Message that hangs forever. I bought this app specifically for this feature and since its not working at all, Im not a happy customer. Additionally, their documentation of this feature and other advanced features is very poor, which is also unacceptable considering I paid good money for this app.
