I went for a while without playing arena because I was frustrated with the current standard meta, but I wanted to start back with Historic today. I downloaded the update successfully, but when I booted the game up, it prompted me to change my password. (I don't know for what reason) I tried. Several times. (on my PC and phone) I keep encountering the same issue/ error -Unknown Validation Code- message. I apologize if has already been answered here. Help please. Thanks.
