ADE Keeps Re-downloading Each Time I Download A Book

I'm a member of first to read and each time I go to download a book I won it re-downloads ADE but not the book! Does anyone know how to fix this? I've only been able to download one book so far and since then nothing because ADE just keeps re-downloading itself. I have started to cancel the new downloads and then a window pops open saying I need administrative access.

Any advice or guidance is appreciated. I have several books I need to review.
