--- Comment #3 from David dav75uk@yahoo.co.uk --- As of wine 7.20 Chessbase 11 activates. When entering the code in the prompt box, it no longer pesters for an activation code.
Things are still a little inconsistent as if you open the admin tool it says it's not registered.
At least now I've not got to worry that the app will shutdown on me, and no longer have to workaround.
I'm assuming this fixes the problem in Chessbase 12 but I don't have the software to test. Could the original user (dbacc@posteo.de) retry and if so this can be closed.
