So I just purchased Divine Mysteries, and the single file PDF isn't there. Every time I try to download it, I get a zero kilobyte .zip thing that can't be opened. The 'file per chapter' version is fine, it's just the single file version that's wonky.
Definitely send an email to our Customer Service Team! You can reach them at customer.service(@)paizo(.)com, and they'll be able to help you get your purchase!
