Can not connect RDS server connection

I have been trying to get this extension to connect to my colobox for the past 6 hours with no luck.
Server Connection Settings in Dreamweaver CS4 look as follows:

Name: ip address we are using
Access Type:RDS
URL Prefix: ip address we are using

Host Name: ip address we are using
Port: 80
Full Host Directory: c:\inetpub\wwwroot\cfide
username: set correctly
password: set correctly

I really would like to be able to get the product going and use it.
Any help is greatly appreciated.
Thanks

Updated Full Host Directory setting to ip address we are using. Still can no connect. Error says that the url appears to be invalid (it is not invalid).

if the URL Prefix is set only to use the ip address, this will not be valid.


the url prefix must be a complete http address to access the site on the server:
192.168.1.1

for example, it must include the http prefix.
