I cannot open my Lightroom catalog. I tried the workaround suggested here https://forums.adobe.com/thread/2046263 to create a new catalog and then try "Import from another calalog ..." but that did not work and I got the message "The catalog does not appear to be a valid Lightroom catalog."
Please advise. I am runnig Windows 10. I have Creative Cloud Account so I believe my Lightroom version is the latest one (?)

Exactly what happens when you try? Please give details and quote the complete unedited word-for-word error message.
Please state the exact version NUMBER of your Lightroom. Go to Help->System Info to find the version number.
