Cynosa V2 missing keys

Hello ! It's been a few weeks (about 1 month) i got the Razer Cynosa V2, and everything worked fine since now, i don't changed anything, the keyboard seems totally fine, nothing spilled into, and i don't hit it (just typing normally), but since today, i pluged it to my laptop, and since, my keys (F1, F2, F3,F4, F5, F6, F7, F8, F9, F10, F11, F12, System screenshot, stop scrolling and the small 2 on the top left, AZERTY disposition) don't work anymore... And i tried the keyboard the first day i got it, (on my laptop and my desktop) and it worked fine... Thanks for reading :'(
