--- Comment #2 from David dav75uk@yahoo.co.uk --- Unfortunately they don't do a demo or a free version, nor are interested in working with wine (as they believe it will lead to a support burden).
ChessBase Reader 17 which was developed 5 years prior doesn't suffer from the same problem either.
It could be an installation issue, which is why getting the problem with the install key fixed is probably a higher priority, as perhaps a local install rather than a copy from a windows install might fix the problem.
Happy to arrange a zoom call with a developer to run through some tests or try out stuff to help diagnose the issue.
