I had the same problem, looked everywhere and couldn't find a solution but here's how i fixed it.
Go to: https://www.ttesports.com
Scroll down to the bottom of the page
Under "Support" you'll see "Downloads & FAQ"
Click "Keyboard"
Select "Challenger Edge Pro RGB"
Download the file that comes up. It has a different release date to the other download and this one works, well for me anyway. Good luck buddy!
