The Gerber Viewer appears to be broken - when submitting manually I get errors like "Unexpected JSON at Position 4", and when submitting through the PCB order form it times out when attempting to render the gerber. I've tried with both new and previously ordered boards, so at a minimum the previously ordered files should be OK.
