Can't duel

I can log-in fine, but when I try to enter the lobby, the giant green arrow that is usually there is now a grey line. I am using Google Chrome.

I cannot see your image, is your deck saved as your default?
Does it have 40cards? none banned? Try resaving it,that helped for me once

We have a Camera on DN that you can just click and it'll take the screenshot for you.

Could've saved you some time, plus the fact that yours didn't work...
