Doesnt work anymore

I purchased this for my iPad several years ago and had 382 books in my list. Now I am unable to enter new books. There is some sort of filter window instead of the input window where I could search by ISBN number.

Then I tried to export the data to my iPhone and am unable to do so. Book Crawler is now worthless to me unless its fixed with a new update that improves it (or at least returns it to the version I knew and loved).
