Think something might be going on WCGs server.

Contestant #1 is in PV status (Contestant #0 = "No reply")
Everyone is now erroring out -- up to contestant #8.

Got the same error on the next WU too, a MCM one:
MCM1_0007480_3560

and again have an earlier contestant in PV status, and everyone else now erroring out.
