Postin' my code here with link if anyone needs to use it. I edited my previous post. Also "My Account" is finally workin' for me which wasn't since the promotion started.
I used this one, since I entered the wrong thing for another referral.
This time I did the left side of the Vita. I took out DC and it finally worked for me.
I typed it in just like that.
Edit: I don't even know if what I entered was correct now lol.
