cannot save illustrator files due to lack of embedded fonts
I installed one license of my Adobe Creative Suite (v5.1) on my new Lenovo X1 Carbon laptop with Windows 10, and cannot save Illustrator files after Placing PDF files. I get the following message:

I've never seen this error on any of my other systems with older version of Windows (but the same version of Illustrator) when I perform the same process. That error points to a font that I don't believe exists...
Thanks!
