I had the came problem happen to me when I reinstalled windows. I forgot to reinstall the IP auto updater app, and my IP address had changed without me realizing. It took me a little while to figure out why my IP's didn't match.
So you need to install their app or go to their website and manually update your ip address.
exactly what swflutka said. you need the updater app on your computer (or any computer on your network).
