violetkitty87Hmm interesting problem. I have Win 8.1 on my computer and the keyboard worked fine for me. You can contact support about possibly replacing it if it's a defective unit, but not sure how they handle returns.
Any other 8.1 users out there experiencing any problems?
violetkitty87I don't believe you can... I know that someone did leave a response about Windows 8.1:
"To those having issues on windows 8.1, I found a solution that worked for me. Uninstalling the driver did not work for me, however manually updating the device driver did. In device manager, find, and right click "ND-Tech USB Adapter" and under "Driver" click update driver. Under "Let me choose from a list of..." I opted to try the "USB Composite Device" driver, and that got my keyboard up and running. Good luck everyone!" (SeaPancake3)
