Book and Packaging PDF links broken

[cjm32123315]

Hi all, a real puzzler here.  When i create a pdf from a book or when packaging the files i get super low res, pixelated images like if the links were broken, both PNGs, jpgs, and AI all look *.

But... if i create a PDF from the seperate files they are fine... which gives me a work around but not ideal with 16 parts to my files to collate every quarter.

Things i have tried:

• Trashed my preferences
• changed adobe profiles, standard and customised 
• tried both interactive and print pdf in different resolutions
• yes the links are fine
• deleted the book file and re-created it.

On a windows 10 PC, running the latest CC.

You're using the Export PDF command from the Book panel?

Hi well yes, it happens when i export the book from the books pannel and when i package a file, and include a PDF.

Thanks, i just completely reinstalled indesign and that seems to have fixed it.
