Our CAPTCHA is broken on the forum, so if you're a new user, you will not be able to download anything until I make a new account for you manually.
Just email me at mark@audulus.com with your desired username and I'll set you up with an account!
Sorry for the inconvenience - we'll have this fixed sometime next week. Until then, just write me mark@audulus.com and I'll get right back to you with a new account!
