Note in addition to the above: When using the license reset tool, make sure you explicitly run the Command Prompt AS ADMINISTRATOR -- simply running it from an administrator account is NOT enough. And make sure you type in the required commands correctly (including the spaces -- even an extra or missing space can throw it off).
