If you choose Setup an Account, does it walk you through the Firm Information screens?  Thats where I got stuck at the end of the Firm information, I couldnt see the last info boxes that needed to be filled in on the very last screen (I kept hitting that Sign in button and nothing would happen!!) it looked like everything was completed and filled, until I scrolled that last screen down another inch , then the Efile Contact Name boxes appeared, once I filled those in, I was able to click Sign In and move forward.
