I've updated to the 2021 software. -And un-installed/re-installed- but still having the same issue. For some reason Ai will not let me save my files as .ai. It works to save it as a .eps or .pdf but freaks out anytime I try to save ANYTHING as an .ai. It's the same for newly created documents and trying to save updated files from previous versions. I'm not the only one on my team having this issue.
Also myriad pro isn't reading either. Just shows up as blank space. The text is there just doesn't show anything. Not sure if that's connected just wanted to voice that point.
Where are you saving files? If not on your harddisk, please try that first.
Didyou reset the preferences after updating? Please do that as well (rename the folder): https://helpx.adobe.com/illustrator/using/setting-preferences.html
Do you use font management? It might need an update.
Thanks! I'll give this a try.
I'm having teh same problem with Myraid Pro - just shoing as blacnk boxes with no way to edit
I just updated my preferences with the keyboard shortcut and it fixed my text probelm - - Alt+Control+Shift as you open Illustrator
