Topic: Fireface 400 crashing in Mountain Lion

Hi everyone.
My fireface 400 last week suddenly began to crash (between a sound check & a gig...I did nothing).
I tried every driver. The other day the freq in System clock was insane. Today freq is all right.
That's on a Brand new (from last month) macbook pro r 2,9 GHz Intel Core i7 with 8 GB of RAM.
Graphics Intel HD Graphics 4000 512 MB. OS X 10.8.2 (12C3103).
When I use the fireface with my iMac at home (snow leopard), no problem at all.

Thanks for any help.

Arecio
