This error will occur if you update your copy of A-Shell with a version that was released after the maintenance expiration embedded in your license key. To check your maintenance expiration before downloading an update, you can use ABOUT.LIT from the A-Shell command prompt, or in the case of Windows, you can also display the Help...About dialog box. The release date of the update will be displayed on the web page along with the update file.

Note that the maintenance expiration does not limit you from running your currently licensed version of A-Shell. It only prevents you from running a new version generated after the maintenance expiration. To avoid this problem and gain access to all updates, at all times, contact your dealer or MicroSabio to renew the maintenance on your license annually.
