Content still locked after purchase

I bought this app some time ago. Its a cool little app, if you wear ties and formal attire frequently, like I do. It is a bit over-priced, but I had the cash to spare at the time of purchase, so no big deal.

At some point, though, the app seemed to forget I paid my $5.99. Now, when I attempt to use the app, I am faced with incessant advertisements and locked content. Its a shame, since it turned an otherwise cool little style idea into a total waste of money.
