<p>welcome to the GPGTools support platform. Sorry you are having problems using GPG Suite.</p>
<p>First, let's check if your key is ok:</p>
<ol>
<li>open GPG Keychain<br></li>
<li>double click your sec/pub key<br></li>
<li>create a screenshot of the <strong>key tab</strong> (⇧⌘4 + drag w mouse)<br></li>
<li>create a screenshot of the <strong>subkey tab</strong><br></li>
<li>attach both screenshots to your discussion by visiting it in your browser</li>
</ol>
<p>Should your key have expired, please re-new the expiration date.</p>
<p>Should your subkey be expired, please create a new subkey.</p>
<ol>
<li>navigate to the subkey tab<br></li>
<li>click the "+" button below<br></li>
<li>confirm with "Generate subkey"</li>
</ol>
<p>After that send a signed and encrypted test mail to yourself. Are you able to decrypt and verify the signature successfully?</p>
<p>In case your key resides on the public key servers, don't forget to upload your updated key, so that the changes are reflected on the key servers.</p>
<p>Best regards,<br>
Steve</p>
