I'm doing the the module "Session-Based Permission Sets and Security" and have become stuck on the project for the section called "Activate Session-Based Permission Sets Without Code." Everytime I have checked the challenge (even using a new Developer Edition) I get a red bar at the top of the challenge that says 

Challenge Not yet complete... here's what's wrong: 
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: SCRIQBYX

Any help would be greatly appreciated. I can give me details if needed. Thanks!
