Same here, it finally let me log in for just enough time to spend all my credits on boss fight, get in first place, then freeze battle at 9% while i watch everyone pass me, if i refresh it just sticks at 100%. Kudos for an entire day wasted and going down in credits yay. I'm now stuck at the circle where it still says loading boss fight at 9% and can't move. If i refresh I know I can't get back in so I guess I'll just sit here and think about my credits spent and what items I would have got if the game worked properly.
