Same boat. I'm going to keep trying and hope for the best, but there's only 2.5 hours of Free RPG Day left - assuming of course that Green Ronin, like me, is on Pacific time.
Poor sad overloaded servers. Good news for GR, at least - they seem to have some good visibility!
I found an email with my order in my inbox this morning. It seems one of my tries to get the files before (the one that almost made it yesterday morning) made it through. The files all downloaded quickly, and I'm quite enjoying them now.
Perhaps GR could be super-nice and send out the PDF to accounts created yesterday, as pretty much any account created yesterday was for the purpose of getting it?
Oh, and for those of you who DID get it - if you have any questions/comments regarding True20, hop on over to the True20 boards (www.true20.com/forum) and there'll be plenty of people who can help you out. There are also a number of decent fan setting conversions over there -- I know I've seen Tamriel, Narnia, Star Wars, Avatar, and a few others recently.
