I have been using the app and two games HotPot and GalaxyRushroom are not working for me. I am not able to download them and add them to my library. I see a similarity between them though - they both are contained in zip files. A lot of games are I think but every game I downloaded so far are just in folders - nothing like a zip file. Other than that I'm not sure how or why I'm not able to download them.
