Sudden error when trying to start Trados Workbench

Hello,

I'm a long-time user of Trados Workbench (SDL Trados 2007 Suite Freelance), and I've been using it almost daily since I bought the product in 2008. However, when trying to start the application today, I got the following error message:

An error occurred while trying to verify the license.
Please check the installation and try again.
Translator's Workbench Freelance will now close.

I don't know what caused the problem. I recently updated my Studio license to Trados Studio 2024 Freelance, but I've been running both programs in parallel without problems since then. Also, it doesn't matter if I have Studio running or not.  

Could you please help me, because I haven't found any solution top the problem, despite the fact that I have reset my license and tested the solutions I found online.

Kind regards,
Björn Dahlborn
