gpg problem: unusable public key

[PROBLEM]
I wanted to encrypt a file, but gpg gave me the following response:
[SOLUTION]
My key had expired.
Ken Newquist's Blog at Lafayette College showed me the steps to do it. Unfortunately, I still got the same error message
The reason was: My main public key could only sign, and my subkey could encrypt - but was still marked as expired. Thanks to a
post on gnupg.org by Charly Avital, it was trivial to revive my subkey, too.
Now, encryption works fine again!
