Data Model damaged in all workbooks

[lingerman]

I use Office 2013, and often create pivot tables that require I check off the "Add this data to the Data Model" box when selecting the data range. I know that this can only be done in an excel workbook (and not a CSV, etc.) and have never had an issue building this table before. Suddenly, every time I try to add the data to the data model, I get an error that reads "We couldn't load the Data Model. This may be because the Data Model in this workbook is damaged." I've received this message on multiple, unrelated workbooks and cannot figure out what might have happened. Can anyone provide insight?

Many thanks in advance!
