Can't import Adele's public key

I sent an email to Adele and got the reply which I decrypted fine. I see the message on my MS Outlook and I am able to read it.

Then I copy the text between the lines…

-----BEGIN PGP PUBLIC KEY BLOCK-----
block of text here…
-----END PGP PUBLIC KEY BLOCK-----

Including those begin and end lines, and I paste it on a new notepad file. Save it with extension asc and them try to import it through Kleopatra but it fails. I get a pop-up with the import result which says ‘Total number processes:0’

What am I doing wrong?

Thank you very much for your help in advance.

Ah! I am using Kleopatra version 4.1.4
