Own A Key but impossible to reach Buddy Store

Hello guys :) (Sorry in advance for my english, i'm from France)



So, i bought a key for a while with a friend (2 years ago i think, it was at the beginning of cataclysm), and with the new system (BuddyStore & Buddy Auth) I don't know how to allow me to download & purchase produits in the Buddy Store.

The guy which i bought the key doesn't play WoW anymore and i haven't any touch with him...



So, how can i access to the Buddy store for myself? With the key i own ? :)

I've a AuthBuddy Account with the same Nickname too :)





Thanks you
