Wont Detect Mbox, my protools LE 6.7 dosent detect HW Options

[roli_rd]

Hey i was wondering if someone could help me with the following: i recently bought a PB G4 1.67 GHz it comes with 10.3.7 OS i also bought Mbox factory bundle. I installed all the software but Protools LE 6.7 dose not detect de HW (Mbox), i tried Reseting it, disconecting it, reinstalling it. All the leds light up plus reason adapted detects the hardware and Garage band detects the HW also... so im not really shure what changes i have to do t get the Mbox to work with its respective software.

i'd apreciate the help
