PocketCloud Error Message

I recently purchased PocketCloud Pro for Android from the market and installed it on a Samsung Galaxy Tab device. I manually setup an RDP session to connect to a W2k3 server system. Everytime I connect I am getting an error message tells me the application is not licensed and to please purchase it from the Android Market. It offers 2 options; buy now or exit. I am working behind a firewall and can not connect to the android market from this network. If I connect to the internet on another network the app works OK. Anyone else seen this and have a solution?
