Hello,Font Cache troubleshooting
If your fonts are not appearing correctly in the font menu or in documents (“garbled” is a common term for this), then one of the best solutions is to clear your font cache. Depending upon your system and application programs, this may entail deleting multiple font cache files.
What is a font cache file?
These are files used by the operating system and certain applications to keep track of what fonts are installed. If the font cache gets corrupted a variety of problems can ensue, including fonts not appearing in the font list in an application, or wrong fonts (or missing fonts) in documents.
How to clear the font cache
The best approach to delete the font cache file(s). It’s OK to delete these files, as they will automatically be restored once your system is restarted, or when you relaunch an application.
The Windows operating system has a font cache file that is located here:
Delete this file, and restart your system. A new FNTCACHE.DAT file will be created on startup. Source
Disclaimer... I personally never had a Font problem, so I've never tried this. However, the source is correct to state that cache file(s) do get recreated at Startup. If you are wary about trying this solution, please at minimum, create a System Restore Point first.
Note that the program you just updated may have a font cache also and it may have been corrupted when you updated the program. I'm not familiar with your program, but you may need to check it out.
