Sorry, you can get no help here. As far as the email address no longer being valid, contact the Brazilian government.
Regarding the 10-digit code, it would not be much of a security system if we could give you the code. Once used, the code is your problem to control and remember.
Sorry, but that is the way it is.

I understand that you are having problems logging into a Mobo 5900 unit, I apologize for any inconveniences.
Regarding that, first I would like to mention that Intel ® provides the processor so that the unit can operate properly. We do not handle any type of "Login" system so we do not have any way to provide you with an unlocking code.
Also, this unit seems to be manufactured by "Mobo" so it is recommendable that you contact the system's manufacturer and see if they have any advice to unlock and/or be able to use the system properly.
