I was installing the Hardware Manager to change the Channel and Update the Firmware on my Box. I found the missing dll-file on the Internet and installed it on my pc. Now I can access the box. So now I can connect the Box to my IPad on a Channel not so busy as number 1. This was one of the recommandations from the video. I will find out if the operation helped, when Iām playing a gig with my band on Saturday. Thank you for helping šš©š°
