Hi LuigiM81 and welcome to the community and the forum!
Sorry to hear about your difficulties. Well, you’ll know what to do: get in touch with FP Support as soon as possible, I hope your experience will be dealt with as efficiently as for BlackFoxglove
I also hope you have a backup of some kind if they’re obliged to change the motherboard.
Good luck!
P.S. - I just saw another thread through a link from Karsten, looks like a similar problem.
