New computer...new install of XWD...upon opening my .web file constructed with XWD on old computer...why am I getting the following warning message:

"Warning from XWD:

This document contains fonts that are not currently installed (Martina). It will display and print correctly using embedded subset fonts but editing may result in a substituted font being used."

I am not aware of purposely using Martina font in the file. Was it part of XWD, and why don't I have it now?
