For the past two weeks now I have been working on 2 different projects in Indesign each of them have taken a complete day of work! They all of the sudden InDesign starts acting weird like not being able to use command z and will not let me save my document, I have been saving with PDFs as well for these projects but the PDFs do not open either! They say they are damaged?? I'm really frustrated at this point, I have a new Mac so it shouldn't be my computer.
Which version of InDesign and OS?
