Anyone here got Bloody series mouse (I have r80) ?

How the hell you make the "sniper rifle" button work ? The button is set, the DPI is set and everything is downloaded to the mouse but pressing and holding that button doesnt lower the dpi at all

The side button is not damaged, it functions properly but it just doesnt want to cooperate with that "tech". I mean this is like the only useful thing here in the soft (and hey, if you want to use macros you got to pay for that extra functionality xd wtf) as lowering dpi while sniping can come in handy but it just doesnt work
