We are aware of the issue. It will be fixed soon be patient.
As a reminder, you can always download again those files via your PinDIY profile, they are registered there for you to download again as many times as you need once you paid them, just need to wait until the problem is fixed.
I bought this file:
Created by Craftychick - Jenny Ryan - Musical Gnome
but can!t download it, it says Attachment is not exists or unable to read, please contact administrator.
This is happening to me as well. I thought it was one pattern being a fluke, but then it happened to the next thing I tried too. I'll just favorite them for now and hope it gets fixed soon.
