[Gpg4win-users-en] Error when decrypting a file with kleopatra

trying to decrypt the file gives me the following error message on my linux command lone (I get the message in german however this is what I would suppose the english equivalent would look like):

gpg: encrypted with RSA key, ID ****
gpg: encryption failed: no secret key.

So this looks fine to me, too.
I think there really has been either a transmission error or he is trying to encrypt the wrong file.
However we already sent him the file twice and asked for the MD5 sum yesterday. We are waiting for a response on that at the moment.

Thanks, I'll keep you posted.
