Hi, my keyboard has only 1~2 weeks of use and I'm loving it, but I noticed a problem on the second day. (After updating firmware)
The F10 light is not matching with others, I found a video with the same problem after searching through the forums:
Funny thing is, when my Windows is still booting, it seems to works perfect. I already tried to reinstall the software. Five times!
I am currently living in Japan, also Japanese version of the keyboard.
Any support is welcome! Thanks so much!
