Interactive books – Interactive Touch Books - for Kids Review

As soon as I purchased a fourth book, two previously purchased books are grayed out. I can no longer open them without purchasing them again. What's the deal? My granddaughter loves the lost books. Mr. Magic's Magic and Bunnyfur's Easter are great. But no way do I want to pay for books again. Also where is technical support for these apps?
