[windows key don't work]

Hi,

 

I just bought the Challenger prime keyboard

(http://www.ttesports.com/Keyboard/156/CHALLENGER_Prime/productPage.htm?a=a&g=ftr#.Vp6_2PnhCUk)

 

I've installed the software, everything runs ok (it is very slow to apply changes but I can live with that), but if I configure ANYTHING in the software and apply changes, the left windows key don't work anymore. If I turn the settings to default, it works again, but any changes I make, the problem appears again.

 

I'm on win 7 64 SP1

 

Thanks,

 

Walter
