Cannot get it to work!?

[marc]

Hi guys,
I am using Ubuntu 12.04., Thunderbird v.17.0.7, and enigmail-1.5.2-tb+sm. I am able to decrypt the emails of a friend whom I have swapped keys with. But there's no way I can encrypt my emails. Get the message:
"Das Senden wurde abgebrochen - Fehler Verschlüsselung fehlgeschlagen" (Could not encrypt). Have been trying and trying but can't get it to work :(

What does the Console (OpenPGP -> Debugging Options -> View Console) say?

You try to use the secret key 0x6FCA7481, but it's not on your keyring. You should go to Edit > Account Settings > OpenPGP Security; then click on "Select key" select a valid secret key.
