MakeMKV asking for registration and not accepting the demo license

[youlk1234]

Hi there,
My MakeMKV (on Tiny11) started asking today for a license. Since i didn't pay for one (i don't have the means) and the software is still in beta, i used this license: T-BSaJ6gwgMx4eIggWkVYXiVP_6zehm7WAO9dEydvzOHFHoZ6YQ82BL5cGpYDxvyRWnS which is the one provided free until end of June 2026. But it calls it invalid. Any ideas on how to fix it?

How did you enter the key? Did you use Copy/Paste?

If so, windows users (especially) have to be careful that Microsoft did not "grab" too many characters.

Copy the key from the web page. Paste it into (say) notepad. THEN copy and paste the result into MakeMKV. This breaks Windows "helping" with the C/P operation.
