Symantec Desktop Encryption - Keys always disable

Hello all,

I have the product installed on a Mac computer using Mail email client.

The problem is that always I turn on the computer and I try to send a encrypted message, I receive a error from the Mail SMTP connection. I have noted that the Keys are all Disable on the Encryption Desktop. I have chanfed all keys Enabled and then the message goes encrypted. The problem is that I have to do this process everytime that I turn on the machine.

The question is: Is it possible the keys are always Enable automatically? Why it happen?

Thanks a lot.
