Cant see linked excel spread sheets when viewing drawing with edrawings

Using solidworks 2012 with EPDM. Link an excel spread sheet from our electrical dept. to the drawing. Elec dept updates the spreadsheet which updates on our drawing page (in solidworks). Other departments use edrawings to view and approve drawings. When drawings are opened with Edrawings 2014 the page has rectangular blocks where the spread sheet should be.
