Your pedal needs a little update.
The LEHLE VERWALTER doesn't support your device's current firmware (V
01.XX), but needs V01.15.
To fix this, you'll need to update it manually using the MSD (USB mass storage device) mode.
Once you've done that, just reconnect your pedal, reload the LEHLE VERWALTER and update to the newest available firmware in the VERWALTER.
Then you'll be all set to configure your pedal!
You can find all the details on how to update your pedal via MSD at

Currently, the LEHLE VERWALTER doesn't support your device's current firmware (V
01.XX), but needs V01.11.
