I need some answers for this, I go to dewxp.com and go to dashboard but it will not allow me to sign in my xbox live account and therefore I can not apply the Double XP.
The dewxp is really glitchy. This happened to me and i tried it again 2 days later and it worked. Just keep trying…
I went on to apply some codes today and it gave me a few issues getting logged in but after a few minutes it worked and i used them tonight with no problems.
