Hello Miss Angel Faith,


It should work.


Just follow these steps:


  1. Make sure to log out BOTH from iTunes and App Store and have BOTH of them closed.
  2. Open Terminal Comamand
  3. Copy the whole string and press enter

defaults write com.apple.appstore.commerce Storefront -string "$(defaults read com.apple.appstore.commerce Storefront | sed s/,8/,13/)"

4.Open App Store and sign in to your account.
