Engine Library not available anymore after opening Rekordbox

Hello everybody, I was uploading new songs into my Engine playlist (as usual) and I needed also to update rekordbox because for some nights I didn’t need my equipment and I would find already a Pioneer setup. As soon as Engine and Rekordbox started together in my laptop, they went into a kind of conflict I guess. Now engine doesn’t have the library anymore. can someone help?

Have you tried to reimport the rekordbox library?
