8.0.16: Tab;es could not be fetched (1 reply)

Upgraded from 8.0.15 to 8.0.16 on Win 10.
On both my databases, there are error messages in the left/Schemas column saying:
Tables could not be fetched
Views could not be fetched
etc.

In one of the DB's, queries work even with those errors.
In the other, the query reports that the table does not exist.
Both DB's exist and work perfectly fine when tested on the host.

Suggestions?

Also, I tried to re-install 8.0.15, using my past msi file, but the installation just hangs. How do I install a prior version?

Thanks!
