I can only post 1 game on the Scirra Arcade

Hello,

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?

Thanks

Tom already knows that the Scirra Arcade upload is broken, he said it won't be fixed since they are working on a new platform.
