Studio 2019: Activated installation suddenly says: 'Evaluation Expired'

Good afternoon,

My installation of Studio 2019 was activated with the appropriate licence key on the day of release (25 July). Suddenly, I cannot run the programme. It stops with the message 'Evaluation Expired (26)'. But I have never run an evaluation version.

When checking my account, it says there is one licence in use. Indeed activated on 25 July.

How can I resolve this, please? I know I can use an extra activation, but if I do that, I will have nothing to fall back on.

Please advise.


Best regards,
