It was initially doing this even when I was saving the .ai file. I went to my system preferences and did "Restore default fonts" and it will not allow me to save as an .ai file, but not an EPS. I have also tried converting the text to outlines, and it still will not let me save it.
Help!

Sealyspeak, Frolnocx,
Each time you close down Illy, the preference files are updated; these are the basic one and the other ones and the Illustrator [Version number] Settings folder.
This means that as soon as you have built the preferences as you like them, you may may close down Illy and copy the whole folder to a backup folder; you can also copy the basic preferences file (the AIPrefs/Adobe Illustrator Prefs file in Win/Mac speak), and when you need to reset the preferences in the future you can use the backup version.
You can see how to find the folder and the file in Move the folder and Working with the AIPrefs/Adobe Illustrator Prefs file.
The [Version number] is a bit tricky: up to 10 it is the actual (single application) version number, for 11 to 16 it is the Creative Suite number, CS - CS6, for CC it is 17 (the original numbering resumed).
If you do that, you may still have to reset preferences, but at least you can reset to a sound version of your own settings.
