I can't get latest version of Illustrator 2019 to open up and function. I keep getting this) There is not enough memory to ... appearance of an object. . I had nothing but problems with the latest upgrade when I installed it back in Jan. I got same dialogue (appearance of object) So I reinstalled the previous or older version and it worked fine. A month ago I installed new version with more bells and whistles and now nothing but crashes. Unfortunately I uninstalled older version so it's not on computer. How do I reinstall it?
