we have just bought MOTOGP13 for xbox360E but it doesn't work: after few minutes we receive the following message "ESC THE DISK AND CLEAN IT". We followed this instruction, all the instructions read on the XBOX support web site (i.e. remove from hard disk the game etc..) but the error persists. It is a new console. Could you please help us to solve this issue? Let we know if you need other information about it.
