Can you check if you have the same e-mail address as you’ve registered to the site in this file please:
C:Users_user_name_AppDataRoamingePic Character Generatoremail.txt
I’ve checked it with our end and this pack has been granted to your account, although our system doesn’t show any tries of you logging in, so I assume the above file doesn’t have your address correctly in it.
I hope this help, and I’m sorry you’ve run into this issue. Let us know how you get on!
