よくある問題Can't boost my character, I receive "Internal Error"
Just Upgraded My WoW Account
If you purchased the upgrade in our Shop, you won’t be able to use the free Character Boost until your payment is processed. This should take no more than 24 hours. Please try again tomorrow. You can keep track of the status of your order in your Transaction History.
My Character is a Level 40 Trial Character
It is not possible to use a level 50 Character Boost on a level 40 Trial character. Please use your 50 Character Boost on a different character and delete your level 40 Trial character. If your trial character has gold or items you want to keep, make sure to send them by mail to another of your characters before the trial period expires.
