    Cannot open any of my Lightroom catalogs. "Error occurred when trying to change modules."

    TimOlive Level 1

      Bought a new 2013 Mac Pro and did a new install of Photoshop and Lightroom. Then physically moved my data drives over from Mac Pro (10.8.6), but LR won’t open any of the existing catalogs on the new computer (10.9.5). Followed steps 1-5 at http://helpx.adobe.com/lightroom/kb/error-changing-modules-lightroom.html


      Cannot do step #6 (no access to more than one user at a time).

      Please help.
