Please specify the application you are using.
It sounds like you're experiencing an issue with Adobe Digital Editions. Have you followed all the troubleshooting steps under E_AUTH_NOT_READY in this document: Activation errors? Since you are unable to deactivate via the Help menu, you may try bypassing the activation error by navigating to Users/Library/Application Support/Adobe/Digital Editions and dragging the activation.dat file to the trash (Step 5 in the linked document). Restart ADE and attempt to reauthorize.
In case you need additional assistance, I am moving this discussion to the Adobe Digital Editions forum.
Thanks! I will follow your advice and try it. I hope….
