Problem with MPX USB Interface

[Domi.ST]

Hi Community!
I´m runnning FMS on my Intel MacBook with Paralells Desktop and Win XP.
I have managed to get FMS started with the help of jackbyjohn´s description...
Thank you!
But now my problem:
I´d like to use my MX-12 with a MPX Interface cable. When i put the cable in my Mac, a windows opens and asks me if i want to connect the interface to paralells windows. I click yes and the Interface gets installled in the Hardware Manager. If I open FMS, and click on Interface it gets found on Joystick 1 but if I click on Preferences my moves onto the MX-12 are not showed in the calibration Manager.

I hope you understand anything, my English is not the best...
Thanks!
