Dear Jason, sorry for the problem.
When you connect Xkey with your computer, is the red LED on the back lighting? If yes, that means the keyboard was recognized by the computer. If not, that means the unit was defective.
Please find our distributor in your country and contact them directly, also you can send email to [email protected], we will try our best to help.
By the way, it seems we did not receive your email before.
