Can't use Adobe Acrobat when I have opened a document
For the past three days, I have been experiencing the following issue with Adobe Acrobat: Whenever I open a PDF file (regardless of which one), the “loading wheel” starts spinning, and I am unable to work in the program or close it. I have to “force quit” it using Command+Option+ESC. Both the program and my computer have been restarted multiple times, but this has not resolved the issue. There a no updates available. What can I do to use the program again?
