Tapped Out has stopped

Hi, I have tapped out on my Kindle Fire. For the past 5 days it's come up with the opening screen with EA/Fox etc on it but then after about 30 seconds it closes and comes up with "Tapped Out has stopped" - I have tried uninstalling and turning off the Kindle and then reinstalling but nothing seems to work. Any ideas what could be causing this? at the moment I have had to do it the old way whereby my fiance downloads it on his android then copies it over to my kindle but that's annoying when there is big updates I have to keep doing the same thing....and as it's on the Amazon store I would have thought it would have worked fine on the Kindle.

Thanks for any help.
