After automatic update catalog disappeared.

[wj98429907]

LR updated automatically on mai 23. After this, the library only showed empty windows.

I can not see which was right catalog. I selected the ones that I could see, but these appeared to be only old catalogs. Where did the correct catalog go?

What could have happened?  Wim Jansen, the Netherlands.

Do a system search for .lrcat files. It should be "somewhere". Look at the modification dates to find the good one.
