Fakku! Books Purchase Bug

I just bought some books from the website hard copy+digital and for some reason I can't read the digital versions of the three that I bought which were Peachy-Butt Girls, Alluring Woman, and Welcome to Tokoharu Apartments. I went to the store first to buy them, instead of the main site. Not sure if it's a bug or it's processing the order, but I was wondering what happened.

Post in this thread for help, this should be solved soon

Thanks man
