I clicked every link in every related email like 10 times, still isn't working.
Is this because I put both keys that came with my preorder in? Would that cause a problem?
nah it shouldn't, make sure your game account username is entered in lower case.
Mind you, it could be them holding off. I'm
still patching and it's a very small patch. It is downloading at like 4kbs for everyone

. They might be trying to hold off a bit.
If you can log into account management and see Feature: Open Beta, you're golden, you'll just have to wait it out I guess, if you've done all that.
