A bit lost...

Ok so i needed this app to start/stop a bat file that starts a server from my computer remotely.

Im a bit lost though as to how to set this up, i've read the stickied thread and made sure what it looked like i needed to do (on my computer) was done. (I made windows firewall allow all Remote Desktop stuff etc). I tried to use the auto discovery mode, logged in successfully with my gmail account. After figuring out that the auto discovery thing wasnt the actual remote destop thing (correct?), i went to + on my droid and set up a RDP via the "New Computer" button. For nickname i just put "HP - Will" and for 'host' address i went to whatismyip.com and put my ip into the 'host' field. For Username & Password i put in the username/pw i use to log into Windows 7 (although i log into win automaticly) i even changed my user account name and my password to be sure i entered the right info. For 'Domain', i left that blank. I clicked 'Save' and tried to connect but it said "server not found" or something. I even made sure i added an exception to my routers port forward list, (port 3389 on the ip of my droid that the router control panel detcted).

What am i entering wrong or what do i need to do to get the remote desktop feature of PocketCloud?
