Catalog repair

[Van_Epscheuten]

PSE 20, Win10

I had a power failure and now my catalog won't load. Adobe support staff did some remote support and was able to reload a large part of my data into a new catalog. However, I'm still missing a large number of data for some 5000 picture files (keywords, captions, and the like). A Repair/Repair anyway was purportedly succesful, but even so, PSE reported "Last attempt to open the catalog was unsuccessful. Do you wish to retry ...". If I retry, PSE reports "Please wait while the catalof is being loaded" for at least half an hour. Do I have other options, apart from re-assigning keywords to 5000 files? Any suggestions would be rather welcome!
