If you are unable to claim prizes, enter, or rejoin your event, first try restarting Magic: The Gathering Arena. Should that not work, please follow the steps below:
- Click the “Submit a Request” link at the top of this page.
- Select “Report a Problem in your Event” in the “What would you like to contact us about?” dropdown menu.
- Once all required fields have been filled out, please click on the "Submit" button.
