My caps lock won't work.. I downloaded the drivers.
Although there is a problem, I had an old keyboard before with the CTRL key dead, so I changed the CTRL to caps lock and vice versa.
I used this to change my CTRL keys back to normal, but now my caps lock isn't working.
Urgent help, I'm using a newly bought keyboard.
