I enjoyed the demo, so I bought the full version on Google Play. When it tried to install it reported an Error: " Incompatible with other application (s) using the same shared user ID" I am sure the refund process works fine, but I would rather play the game. I have a Xoom tablet using Android 4.0.4. I tried shutting down and restarting, but it did not help. Can you solve this problem? Thanks very much.
