RIOT: I was selected to be a PBE tester, yet...

...every time I go onto the link I keep getting Error: 500. I got the email today about 8 hours ago, so the error isn't a matter of me being too late. If this error goes on for too long, I fear I won't be able to make my PBE account, and that seems like a real low-blow to someone who's been playing the game for a long time. I'd still like to be a PBE tester, please, so if you can see this I'd like you to fix this and hopefully send me another email.
