    Hi Michael,

    welcome to the GPGTools support platform. Sorry you are having problems using GPG Suite.

    Let's check if your key is ok:

    1. open GPG Keychain
    2. double click your sec/pub key
    3. search for "Validity" in key tab and post the value to your discussion
    4. search for "Validity" in subkey tab and post the value to your discussion

    Should your key have expired, please re-new the expiration date in the key tab. To renew the subkey, click the cogwheel icon in the subkey tab and update the expiration date.

    To test the change, send a signed and encrypted test email to yourself. Are you able to decrypt and verify the signature successfully?

    In case your key resides on the public key servers, don't forget to upload your updated key, so that the changes are reflected there as well.

    Best regards,

    Everything is running now. The subkey date had to be changed.
