Submission doesn't work, says I have already submitted

Hello, this is my first time submitting to the leaderboard.
For some reason it says I have already submitted a reconstruction today and I am not allowed to submit.

As there is not a lot of time left this is a critical issue for me.
Please help.

Hi @TheDoctor,

Please try submitting again, there may have been an error with submission process.

Thanks,
Tullie
