So ive signed up for the dev edition org. Ive tried using my playgrounds. What am i missing? No matter what i do I keep getting the error "Challenge Not yet complete... here's what's wrong: 
The 'Trailhead_Data_Manager' app was not found. Please follow the requirements and ensure the wave enabled org is setup correctly." Where do i get this app? I assumed it came already installed when you signed up for the dev org. Can anyone please help, this is the last module i need to complete the trail. Thanks in advance. 

In the Sales Wave App module, specifically Creating Sales Wave Using the Wizard, there is a step where you use the Trailhead Data Manager to download the dataflow. Whenever I click on Download Trailhead Dataflow I receive the message "No SalesWave App found" and therefore I am not able to select my app. The app was created yesterday but still no luck. Any suggestions?
