Topic: Multiface I gone bad

Hi, yesterday I did the latest update to driver v 4.0 and flash to hardware revision 17/55. I have 2 multiface I cards and  card 2 is not recognized as a multiface but as digiface. Also the host error red light now is constant on that box. Also i get "detected - error" status in settings panel. I tried to hook up that box with different firewire cable and power supply, nothing changes. I also tried to connect it to first pci card but no luck. At one point it said it is has been detected and I could see active audio signal in total mix, but it couldn't be routed to any analog outputs, when I raise level bar i total mix to outputs nothing happens. I then tried to connect firsr mf box (the one that is detected as a multiface and working ok all the time) to both pci cards and that one is working fine on both cards. Am I right if I think that mf box 2 is broken? Thanks!
