Ah, I'm actually not familiar with the app, but if you are able to download the game through your browser you can run it by just extracting the files from the zip and running the game application--it doesn't require an actual install process.
Alrighty. I'll see if I can get it to work in the app in my own time, then. And if I can't, downloading it from the browser works for me.
Thanks, and have a nice day :)
