"Tuner" and internal "DSP" doesn't work on Mbox 3 Pro

[luckydjacks]

Hi,

At the beginning of december I bought a Mbox pro (3G) with Protools 9.
Before installing Protools 9 and upgrade 10, i downloaded and installed Mbox Pro last driver (as AVID told it) => 1.0.19 with firmware 1.0.3.
My Protools 10 works well.
The Mbox Pro control panel shows internal dsp (rev, delay....) and tuner window.

Here is my first problem:
1)I plug my guitar into my Mbox pro ->input 1 => input and master signals are ok.
2)On input 1 -> hardware input FX send + software return FX sends + FX returns + effect duration, feedback and volume -> all knobs turned fully clockwise.
=> no effect sounds out, no signal in FX returns bargraph.

Here is my second problem:
3) When i open the "tuner" window => no signal , nothing happens.

Actually, i don't know if the problem comes from the new driver or my Mbox Pro hardware.

Could you help me to fix this malfunction ?

Thanks
Friendly.
