Remote Joystick and SIOC Incompatibility

HI Guys,
I run my MCDU on a separate XP 64 bit machine and all works fine. There is nothing else running.
I need to run some joystick interfaces so installed the app. This worked well but in doing so
it has stopped me from controlling it with the keys. My keys are controlled by opencockpits
USB keys card.
To get my MCDU running again i have to uninstall FMGS and SIOC and reinstall with out installing
Remote joystick app.
When the MCDU stops working i can see in SIOC Monitor that the keys are being read. They are just
not being sent to the server.
Any ideas would be appreciated.
Thanks
Les

Thought i would try another installation with an XP 32bit install. Still no luck.
Guess the compatability is not 100%. Would have been so tidy to do what i wanted.
JL, if you are reading this, any ideas.
