I have two EU accounts and so I wanted to change one to NA region, which you are allowed to do. However, when I asked Blizzard they said I needed my authentication which was on my box, which it appears I have lost.
They said they cannot help me without that code, so I was wondering is there any way to retrieve it? Perhaps through the Sc2 files i have on my computer.
Many thanks.
(No I cannot change the other one as it was my friends account who gave it to me and he doesnt have his box either)
