I have not used IS for a year or so.

When I try to run it I get the "InstallShield Reactivation" dialog box. The option "Continue using IS without reactivating" (which would be OK) is disabled, so I go with the proposed option "Reactivate InstallShield".

When I click Next it thinks for a few seconds, displays the "Activating Serial Number" dialog box, and eventually displays a message box titled "Internet Activation Failed" with the message "Error 51406 - fulfillment record is disabled". There are options to "Attempt online activation again" (doesn't work) and "Proceed with offline activation". The offline activation seems to work Ok, but when I try to run IS the same problem occurs.
