Unable to change deadzone or scale

Hi I bought WOFF UE a couple of days ago and ran into problems:

because I own a Speedlink AIRROW (same as VKB Gladiator ) I'm unable to map any buttons, I got around that problem by using autohotkey
however:
it is still impossible for me to
- remove old button mappings on the joystick (f.e. clear button1 of the firing function; even after it shows in the keymapping tool as bound to a different function)
- change the scale and deadzone

I'm also unable to change
- the deadzone of my rudder pedals (T.Flight rudder pedals by Thrustmaster)
in the advanced axis controls when I higher the value and save, it shows, but there is no difference still.

So I was able to change keyboard mappings, and assign my axes, but I'm unable to change the buttons (on the joystick) and scale/deadzone of any of the axis.

Also: I hear a beeping when I press a joystick button, as I read in the FAQ that might be due to some virtual joystick, which might conflict with the axes. I'm using trackIR, but I havent found any vjoystick to uninstall not in the device manager nor have I found a vjoy program that would be running in the background;

Thank you guys in advance!

Beeping is probably because you left the WOFF key mapping tool open in the background. Close it after you have condfigured/saved.

As per support mails, if I remember correctly there is limit of 8 buttons built in so more than that usually would need manufacturers joystick software to allow more configuration options.
