I want to export my document as a pdf-file, but suddenly the predefined options are all gone. The only option left is "Define". If I try to export again a couple of minutes later I can get lucky and the predefined options are back just to disappear again.
Thank you for responding.
I didn´t dare to replace the files though. Instead I located the files with the file extension .joboptions under: C:\ProgramData\Adobe\Adobe PDF\Settings.
I then copied and pasted the ones I needed under: C:\Users\evagrane\AppData\Roaming\Adobe\Adobe PDF\Settings.
Now when I choose Export from the menu I see all of the preset options so I hope this solved the problem.
