In a developer org I started with a week ago (09/07/015), I received the following error:"There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: KGJFRXSH"Any help is appreciated.
