Problem with the Sigfox S2-LP Kit: ST Side Registration

Hello, I bought a STEVAL-FKI868V1 but I have a problem with the st registration

i saw this video: https://www.youtube.com/watch?v=JD6UE7ekRxE&t=7s

and follow the steps but when I drag the .bin file to the drive and start the register I can't found my RCZ, that is number 2, it only appears 1 and 3.

Thanks for your responses
