Revert to Illustrator 2016
I made the mistake of updating my Illustrator software to the CC 2017 version and now any symbol I created is a non-editable waste of space. This will cost me loads of time! Please do NOT scold me about not reading some read-me file warning I should have seen before updating. Instead, please tell me how I can revert to Illustrator 2016 so I can meet my deadlines without working all weekend.
