Within a month, I think. Or at least sufficient time that you would have
been able to test the feature. This requires knowledge I don't have --
I expect UK consumer laws and policies enter into it.

Or could the retailer
and/or Chessbase argue that all non-trivial software has bugs, and so
refuse to do so?

It's a question if this is a trivial or non-trivial bug. Since the
functionality was described on an (official?) web page, I think you
have ground enough for believing that the functionality is in fact
present without any errors. If it is stated in the manual, you have
a good case.

The thing, though, is that you need find the error reasonably soon
after purchase.

I'm not sure if there is an implicit promise that such functionality
will continue





I believe there are some extra rights one has if paying by a credit
card. Would these help?

I'm almost tempted to buy a second copy just for the hell of it. If
nothing else, it will irritate the retailer to have to give a refund
under such circumstances. They might then put pressure on the developers
to fix the online database they have screwed up.
