why can't i download pdf statements anymore ?

What do you mean? From whom are you downloading these statements? How did it used to work? What happens now?

We don't have enough information to answer your question.

Plus, you've posted this in The Lounge​ which is not a support forum and isn't specific to any of Adobe's software. So we don't know if you're talking about a problem using software like Photoshop, Muse, InDesign, Acrobat or if you are talking about a problem with some web page where you usually get a PDF to download or if you're talking about an issue with your Adobe account in some way.
