Why FCP will not recognise my camera Sony Z1?

Hi
I am using a Sony Z1 camera NTSC
OS = 10.6
FCP = 7.0

I am trying to capture from the Sony Z1 using HDV o DV and FCP will not recognise my camera.

I really want to capture in HDV from the Z1. It was working perfect and suddenly doesn't recognize device anymore. I have read other threads but I cannot relate them to my specific problem. I would appreciate your help as I am going mad with this pop up: "Unable to Initialize Capture Device" I trashed the preferences and refresh device, but nothing worked!

FCP was set using easy setup HDV
Audio/Visual Settings:- Seq Preset = HDV 1080I/60
Capture Preset = HDV
Device Control Preset = Sony HDV 1080i/60 Firewire

Z1
VCR HDV/DV = HDV
Component = 1080i/480i
i Link Conv = Off
Down Convert = Squared
A/V-->DV Out = On

Quicktime 10.0 (51)

Please can anyone help?
Thanks
