Our responses crossed ...
Bottom line is that I now believe that the source of your problem is that the Acrobat 11.0.10 update did not properly complete. Part of all of these updates is for the updater to delete the Adobe PDF PostScript printer driver instance, install the updated software, and then fully recreate the Adobe PDF PostScript printer driver instance using the same settings you used prior to the update. I suspect that either the initial Adobe PDF deletion didn't properly work and/or the regeneration of AdobePDF didn't fully complete for any number of reasons. It does concern me that your original update should have yielded an error to advise that it didn't properly take.
Nonetheless, glad to know you are fully up and working now!
