Previewing Issue
Hi,
I had been using Illustrator on an old account that run out. I downloaded it again after buying it on an a European website (not sure if this is linked to the issue but thought I'd say in case).
When I'm trying to open files I had previously edited in Illustrator, after a moment, I get a pop-up saying "can't finish previewing. Couldn't complete the requested Operation."
When I press ok, the file turns black and white and is unusable. I looked this up and saw somewhere you can press FN (function) +E, but this hasn't worked for me. Could anyone help? Images attached.
