Hi, yesterdey i've installed k70 mk.2 cherry MX brown. While typing and everyting is oke, but during gaming i have som issues like: While walking forward (holding W) and i press A to left or pressing shift to sprint it stops walking (like cancelling the W command). the same happens with other combinations. like S and D or A or spacebar etc. and i have to press W ASD again to move cant sprint or jump or slide while moving. Please help bcause can't game right now.
