First sorry for my english, try to do my best for a belgian user.
Second, my problem : i was in practice, instal my rig and when i put on my kemper this message appear : "updating analogboard firmware" , after 2min, i saw it's a loop of this message. I read so much in this forum for try to fix it (USB device with lastest firmware, reboot with old some key) and nothing to do, the loop stay.
I've send a message to the support, but if someone got a tips for this ? My shows will begin in 2 weeks, so i really need to fix my problem..
