After installing LR CC 2015, my catalogs are messed up. I did not watch carefully as the programs opened. So a new catalog was created.
I am now trying to connect to my previous catalog. I believe this catalog is LR 5.2 Catalog.
When I try to open that catalog, LR 5 and LR CC 2015 report they cannot open the catalog because it is too new.
There is another file which is LR 5.2 Catalog lrcat.lock. Also a file small file lrcat-journal.
