Becker Ready 50 - Need Help

Hello there

I need help for my friend's navigation Becker Ready 50
He asked me can I update his maps on navigation (they was from 2012), so I take it to try.

First mistake, I forgot to backup old maps, but I backup original software.
Second, tried to copy new map files and I'm getting error message, after popup another window with message with license issue. I tied to add all licenses available here, and this message still remains.

Tried to import all available software refereed to Becker, but most of links are dead, so no success.
Can you help me to add new maps on original software? I would like to add latest Europe TomTom maps

Here are some uploads attached





Thank you!
