Hi there, Back in December when I was running Creative Cloud 2017 on El Capitain with NO access to the online Creative Cloud updater, I tried to open a file saved in Creative Cloud 2018, it wouldn't open. Fast forward to now, I'm running Sierra Creative Cloud 2018 WITH access to the online Creative Cloud updater, that same file now opens in all of my older illustrators. Can anyone tell me why? Am I going crazy?! Thx!
