Fail to connect to atik EFW2 filter wheel

Hi All,
I have downloaded the trial version of SGP and I’m trying to connect my devices.
I can connect my CCD, my guide camera, etc, but I can’t connect my filter wheel, an Atik EFW2, 9 position wheel.
I have already change the usb port, and reinstalled the driver (normal driver and ascom driver comes with the installer from Atik). the wheel works fine with other softwares like Artemis or Maxim.
The error come when I click on “connect” or on “device setting
What I can do?
Thanks for help
