CorelDraw keeps asking me to re-authenticate.

After uninstalling Corel Suite 2019 due to too many bugs, we reinstalled Corel Suite 2018. Now at least once a day when we open Corel 2018 it asks us to login again. This happens to two installations with two different logins/serial numbers on two computers 1400km apart.
