So I got it as a gift, saved order receipt in multiple places,but my friend told me that someone bought her guild wars 2 but then the guy terminated it because he was the one who bought it, all he had to go was go to support. Then she told me when she tried to put a new cd key on it, they won't let her...when she had like a lvl 40 character...so I'm afraid that the same thing will happen...so should I buy a new copy cd key to replace it...?
