If you registered your LED Kit, everything should be available under your account on the website. Members -> Downloads, and scroll down. As long as you added the kit to your account with the registration code you got in the package, you should have everything there. If not, I'm sure you can contact the guys on the support email, with your receipt and they could add it to your account.
