The App is installed from the same Amazon Apps on Blackberry as Kindle I think so there must be a problem here. It is a really old version as well - hope that at least they are going to update it for us. I also tried installing the APK for the new version on my Blackberry and it didn't work - gets stuck at the 'loading scouts' part.

One word of Advice - If you are going to install this or any APK manually first make sure you uninstall the old version on the Amazon Apps store as it can be a pain trying to uninstall it again. In the end I had to delete the cache on Amazon Apps then reinstall the game from there. Although even the app from Amazon is now not working!
