Help needed - Keywords disappeared

Hello everyone,

Adobe did it again.

Approx two years ago after an upgrade a new version the keywords were lost and according to the support could not be restored anymore. I got the advice to better save the keyword file in future - so I did.

Now, after upgrading to the Bridge CC 2018 version the keywords are gone again.

As advised before I copied the saved keyword file from the 2017 version in the folder, where the keywords are saved in the 2018 version and made a restart of bridge - nothing - bridge doesn´t accept the "old" file?!

Any solutions?

If not I have to rearrange keywords for approx 60 thousand pictures.

Thanks in advance.

Klaus
