What you need to do is open up your grips, and take out the 2 screws on the back of the grip frame on the inside that hold the button in place (I think the screen is connected to it too). Then what I had to do is take some good gripping pliers and GENTLY pull the button out, and while gripping it, turning the button (like spin the button a couple times around while gripping it with the pliers, the button on the board) to keep it from getting stuck again.
Why do people do this wanna-be hk thing? I mean hk people dont even play paintball, they just whine and start drama while wearing the ugliest stuff. Seriously you find light blue and pink to be attractive colors for your parents 1500 dollar investment (your gun/marker)? If you want to whine keep it off the field and save it for the internet; O wait! THATS EXACTLY WHAT YOU DO! Haha, if you don't play then don't whine.
