Hello, naidmer.
I don't see any downloadable files on your quest's page, so I have a couple of suggestions that may help you out:
- Not sure if this would cause problems, but if you haven't already, set the file type to either "Book or Document" or "Documentation or Instructions".
- Make sure "Hide this file and prevent it from being downloaded" is unchecked.
The only other thing I can suggest is to double check if you remembered to upload the .pdf in the first place... ;)
