Dont buy

First off, yes the really cool keyboards are more money than the free ones. Like why make people spend more money on a app they already payed for?
Second off, I purchased the spring one, and I did what it said.. Allowed YeahKeys on my keyboard, and it doesnt even show up! When I click on "YeahKeys" keyboard on message, it makes me exit out of my Messages app!
