No longer works – Kalm Sutra - Sex Positions and Love Positions for KamaSutra Review

I had this app and paid for all of the downloads. It was working fine. But, I had to get a new iPhone and now it doesn't work at all. The doors open, but no books open and my paid for downloads are no longer there. The support button on this page takes you to the developers webpage. But, there does not appear to be any way to contact him. Hopefully, the developer reads reviews and can address this for me. If he does, I will update my review.
