Behringer X-Touch One: Error opening Devices

[pegel]

hello everyone,

i have problems with my x-touch one,
after enabling it in midi inputs and outputs
i got an error massage that says
input and output for the x-touch could not be opened.

in cubase and studio one it works fine,
but i dont want to stop using rearoute just
of an controller...

any ideas what it could be?

thank you
