Stuck at loading screen before battle

Hello, I'm trying to enter "Diamonds of the Kobolds" but my game gets stuck at the loading screen. The last two lines that appear on the console are "initializing deck builder". My account name is also archielock.

 

Yes... The only difference is that now I only have one line that says "initializing deck builder".

edit : still stuck, back to two lines saying "initializing deck builder"

 

Everything works fine now, thanks Jon !
