    Catalog opening issues on Mac: "unexpected error opening catalog"


      I am using OSX Yosemite 10.10.5 with Lightroom 6. Everything was working good but today it shows "Unexpected error opening catalog". I tried to create one catalog, it still showing error. Now all the files in light gray which seems like i can't open at all.


      I installed another copy on Windows 7 today, is this why caused this catalog issue? I was told I can use on two machine at least.


      Please help. It's kind of urgent.
