Recently, one of our users came across this (very inconvenient) scenario. FME Server had been configured for Active Directory, and the SECURITY_SUPERUSER_ROLE parameter in the fmeCommonConfig.txt (located in <FMEServer>\\Server) had not been set to a valid DN.
Setting this parameter to a DN that the user was a member of, and then restarting FME Server, allowed the user to properly refresh their license.
If this has happened to you, and you are not configured for Active Directory, or if the parameter has already been set, then please contact the for assistance. If you managed to resolve the situation in another way, please add what you did here!
