registration code invalad

What worked for me is that, beneath that giant link you can click on, there is a smaller link/tab for pre release. Click on that and input your code. It didn't work for me the first time, until I switched the code to all capitalize letters, then I was able to install.

Sadly, I've tried this and it still isn't working. No news from SE or replies to any of my support request emails either.
