Saving issue - the error box pops up...
I was using CC 2017 and went to save my file and a box popped up that said
"This printer driver is not supported by Illustrator"
I clicked okay and it let me go back to working. When I went to save again the same thing popped up. I updated to CC 2018 and when the program opened this same message popped up.
It seems to still let me work in the program, but when I go to save the screen goes black and freezes the program for about 20-30 seconds
