In 2016 I converted many of my vector docs from Illustrator to AffDesigner and sorted out all of the layers, a lot of work. These 2016 AffDesigner docs always came up well but I did not save them since then. Now they will not come up on the latest Designer and Publisher programs. Below is the message I get and the name and date of one of these docs. I have also tried to shorten the name without any extra keyboard strokes. Is this a common problem and if so how do I bring them up to date? A lot of my detail work in 2016 is at stake. Thanks.
