Will Faderport work with my Mac OS 10.4.11 Tiger? (ProTools can see the Faderport under Peripherals)

i just bought a Faderport and my ProTools 7.1.1 can see the Faderport under Peripherals, I enabled the Faderport under Peripherals->Machine Control and Peripherals->Synchronization, but it is not actually controlling the machine.

It is an old, but stable ProTools 7.1.1 system ruing on a MacBook Pro that sill has it's original OS... It still works well...

I was hoping to add the Faderport, but so far no luck. If my ProTools sees it under Peripherals should I be able to get it to work. Or is it simply that my OS is too old? Thank you!
