teamviewer licence.

Hi @Klaas1 ,

Thank you for your post.

Could you please explain it in a little bit more detail? Did you receive an error message and if so, what did it say?

Also this article might be helpful in order to use your license.
Please log in to the Computers & Contacts list with your TeamViewer account to use TeamViewer with full functionality. You can find the Computers & Contacts list easily by clicking on the top left circle with the person inside ① or on the tab for Computers & Contacts ➁ :

Hope this will be helpful.
All the best,
Yuri
