When i try to register license at User Area, i get message that serial number is invalid / unrecognized

Serial numbers of D16 products are formatted as six blocks consisting of four alphanumeric characters each, separated by a minus sign. Like this:

XXXX-XXXX-XXXX-XXXX-XXXX-XXXX

You need to keep in mind that when you receive serial number from your reseller or from our online shop. Be sure that any character isn't missing, or format of the serial number is correct. Otherwise you'll get the message that serial is unrecognized.


Another thing you have to make sure of is that there're NO leading or trailing spaces in the form you put the serial into. It happens very often when copy / paste function is used, that extra spaces are added on the beginning or / and the end of the string. Be careful then, and before clicking next button make sure you removed all white characters from the beginning or the end of the serial in the form.
