D&R webstation with proppfrexx faderstart problem

[westendradio]

Hello we use an airlite in combination with proppfrexx, no problems everyting works fine, but now we will use in the second studio an webstation, also with proppfrexx.
But the faderstart section doesn't works, in the gpio client section we use the airlite control section, in the D&R event mapping with the record section no contact.
what do i wrong??

What is a 'webstation' in your environment?
Does your second studio also has a second airlite mixer?

If it works with your other PC, what is the difference with this second PC?
I assume it is just a connectivity issue. How have you connected your 2nd airlite mixer - maybe via a USB-hub? If yes, try directly or change the cable.
Have you enabled the GPIO client extension in ProppFrexx also on your second instance?
