    Upgraded to Lightroom 6.3 on OS X 10.11.1 can't open library, get "An error occurred when attempting to change modules.


      This error is on my 6 library and i attempted to open and convert my old 5 library again. Have rebooted MAC, and checked permissions on /Library/Adobe/Lightroom for read/write.
