Errors in creating Reader Extended PDF

Cannot create Reader-enabled pdf in Acrobat XI, version 11.0.07, on PC.  My co-workers on Macs have no issues.  I've created a form in Acrobat with several dropdown menus for the various fields.  I save a backup copy so that I can go back to the original file to edit as necessary.  From there, I select File > Save as other > Reader Extended PDF > Enable more tools.  From there I receive a pop-up titled "Enable Usage Rights in Adobe Reader" .  I select "Save Now".  I then navigate to the folder where I want this file saved, and update the file name.  Acrobat then saves a file in the correct location, with the correct name, but gives me an error message to the effect of "Reader Enabled version could not be created".  No reason why, just didnt' do it.  In fact, when I open the file in Reader, all the fields are gone, and there is an error message explaining that the Reader Usage rights have been changed".

Help?
