Action Wizard custom action fails

I have an Action Wizard custom action (used previously in Acrobat Pro XI), which uses some JavaScript to add previous/next page, print and home buttons on every page of a document. This worked well before upgrading to DC, but now fails to complete if the document size goes beyond a handful of pages. I really do need a quick solution to this issue, any idea why this is not working in DC? I have tried to run this same custom action on Mac and PC versions of Acrobat Pro DC with the same result.
