I GOT IT WORKING!!!
Good Grief.....in the end I used the PS3 driver and what made ti work was, just after registering the device a window pops up saying you can now unplug your cable.
At this point, I unplugged and paired the controller and THEN with the keyboard moved back to the main menu to configure it.
Trying to pair the device at ANY other point during the process and it doesnt like it.
Have rebooted and the device still conect and works so it seems stable :D
Cheers for the help.
