I want to pay you, let me pay you! – GliderVerb Review

I have been trying in vain to upgrade to the full version, and I assume the ability to do this lies somewhere behind the wrench icon... However, every time I try, the program crashes. Is this an iOS 8 problem? Get that last star guys, help me help you to take my money.
