I can't login!!

Hello,

since I have no idea how to solve this problem I ask here
When I start duelingnetwork.com I get the two boxes, one of them is the login box and the other one is the box with the news, the links etc.
Between these boxes, there is a blue line. Normally, this blue line gets changed into a "Duel"-button after loading, but in my case, it gets stuck at the blue line, even if I try to start it again or if I log in. And obviously, it doesn't matter how long I wait.

Can somebody please help me with that? I would be very thankful

edit: Oh lol, now I've tried it again and it gets stuck at BLS + the information box.
