Hi Uli and Torben
We have a problem in one of our locations with mAirlist , due to a windows update the computer changed the hardware id . Strange thing is that it also lost the D&R Airlite remote control (home version) my collgegue did pay for his version of mAirlist the remote licence .
I already sended a email to support , with the hardware id and licence number
I hope you will be helping out
