No one? Am I the first Keylab25 owner to encounter this issue? No way!
Hello. I bought a Keylab on Amazon lately and received it two days ago. Seven or eight keys are like yours, plus the screen doesn't work. More than 48 hours after opening a ticket, and after insisting, Arturia asked me what the problem was. I'm waiting for a reply, and hope they will do something.
Really frustrating. Unbelievable this happened to you after normal use. You must be frustrated too.
