    Lightroom 5 preview cache error



      I have a new problem with an old issue. I have read as many threads as I could on it and cannot seem to fix these issue.

      I had been using LR4 and added new drives to my Mac Pro 2009 OS 10.6.8 w/48RAM

      I started getting the the "LR encountered an error when reading the preview cache and needs to quit" message.

      I have since installed OS Yosemite and installed LR5.2

      I followed the instructions to delete the Previews.Irdata and then get this message Screen Shot 2015-05-02 at 11.06.36 AM.png


      I have older catalogs from LR2,3 and 4 on another drive. Please don't laugh, I have no idea what to do.

      There are .Irdata files in most of those folders too.

      What do I do first?


      I appreciate any suggestion and support.


      Thanks RPT
