Protools After Update, Doesn't recognize MIDI anymore Options

[kd_rome]

Hello,
I have a mac G5 2 GHz and a Digi 002.
I just updated ProTools to 6.4 and the software doesn't recognize my MIDI Keyboard anymore.
( it's a Roland PC-300 )
If I load a virtual instruments in standalone mode or in Cubase SX it works but if I load it in ProTools it doesn't receive the signal.
I tried to trash all the preferences, repair the permissions, but it doesn't work anyway.
The PC-300 is connected to my mac trought a USB port.
Thank you.
I have also downloaded the update the profiles for legacy MIDI controllers from digidesign
