Call PocketCloud from another App

I downloaded the free version of PocketCloud and it works great, connects without a problem. Now I’m trying to see if I can kick it off from an App I’ve created. I have a button for a VPN connection and another for starting up PocketCloud. After successfully making a VPN connection I then click on the button to startup PocketCloud I get a message box that says, “The application ... has stopped unexpectedly. Please try again.”. Then it does a Force Close. Is there a way to do this within an App using the free version? If I can get it working I would like to purchase it but I first want to see that it will work before buying.

thanks for you help.
