I am getting the following error when I try to use the proofing feature of the extension. While in InDesign, when I hit the Create Proof button, it says:
Failure to export PNG: invalid page number specified. This happens even when there is only one page that I am trying to export.
It works fine on a different computer. The versions of InDesign are the same on both computers and both users have the same access level.
Any ideas on what could be causing this?
