PDFs saved from Tessitura to PC format text too big

The title pretty much says it all. We upgraded to Tessitura v.15 and now for some reason when I save reports as PDFs the text size balloons about 6 sizes too large and it becomes unreadable. I can view and print them normally but saving them messes it up somehow. This does not happen to our other users. What am I missing here? Any suggestions? Thanks!
