Well from my experiences with ydna, A LOT of people email him, and i dont think he wants to be bothered with questions, he would be glad to help but he deals with A LOT of people wanting him to repair there guns. Have u tryed turning it on while the gun isnt put together, just like hitting the button with your finger. If that doesnt work you messed something up with the new button. Check to make sure the there are no severed metal strips on the upper board anywhere, especially where the grip screws go in. Many things could be wrong, check out zdspb.com for answers, but dont email him with the questions. Jus tryina help that guy out.
umm, i like waffles
