I am not sure those still work and the unlocks are zeros not Letter O's - I am sure you know this but just a reminder.
I don't really read Spanish but my experience with the Mackie web links of late has been less than stellar, a lot of them do not work and it is difficult to get through.
I am in the same time zone and have had difficulty getting through. I hope it is working out.
A known good link to tech support E-mail or a phone number would be helpful. Being on the other side of the world doesn't help.
