I'm still unable to log in to Pokemon Global Link?

I've been wanting to go to the Dream World ever since it was up in the states, but since the launch, I still haven't been able to log in. I've made a trainer club account and everything, but the problem is, whenever I log in, it doesn't let me. It just refreshes the page and gives me the blank sign-in screen over and over and over again. What's wrong with this, and has anyone else has/had the same problem?
