Help..need an Aperture 2 serial number to access my library on new computer

I just bought a new computer and have migrated my files but cannot access my Aperture application or library because it is asking for my original Aperture serial number. I have my Aperture 3 upgrade serial number but it wants the original Aperture 2 serial number which I didn't save. I called the Apple store and they said any Aperture 2 serial number will work. does anyone have an Aperture 2 serial number which I could use? I would so appreciate it. I'm in despair/disbelief over this.
