[Problems with the driver]

Hi Guys, since I'm experiencing a similar issue with my recently purchased Challenger Gaming Keyboard (KB-CHM). The issue occurs when I'm switching between accounts on Windows 10. 

 

I am able to select switch account and type in the password for the desired account but once I am logged in the keyboard stops to work. To get the keyboard to work again I require a complete restart of windows. 

 

I have installed the latest driver for this keyboard from your site but to no avail. 

 

Any suggestions from your end?
