I have a problem. Few years ago someone else bought me a key for DSJ4 with a different email address than my own (I didn't had a credit card at this time), but I lost this key and I don't know how to get it back, because I don't have a contact with this person.
Is there any way to get my key back or I need to buy a new one?
My name is Dawid Ciechowski and my email is techno1991@o2.pl
I will be very thankful for the help
