When I try to upload a new game to the Scirra Arcade, It brings me to the game details. The 'Upload File' in the box on the right side of the screen has a check mark by it. When I click it to change it, it doesn't do anything. Also, when I go to the bottom of the page and try to cancel this game submission, it brings up :
Server Error in '/' Application... etc.
I don't know how to fix this and I can't upload any more games to the Arcade (I have only been able to upload 1 so far).
Can anybody help me?
