There is no such thing as a serial for Maestro - it's a DONGLE-only protection, unlike Scenarist which uses both Dongle AND serial protection. Unless you have a dongle, you will need a dongle-cracked build, and if you have a dongle-cracked build (e.g. TFL, SMB, or SSG) then a serial number will not be an issue, I can assure you. You can find SSG's last Maestro release in the DVD-writing section of the downloads on CDRsoft's main site. It's 2915a and that's as recent as Maestro gets, in the Warez world.
