Abbreviation file not being seen by Timeslips Premium after service pack installed yesterday

We recently upgraded from Timeslips 2015 to Timeslips premium.  We installed the first service pack since the upgrade yesterday. 

Now my abbreviations are not recognized.  I pointed Timeslips to the file, but it does not "see" it.  

I have anywhere from 50-100 abbreviations I use every day.  

How do I get Timeslips Premium to "see" the file like it did after the upgrade but prior to the service pack?

Thank you!
