I can't progress pass the first stage on this project.  I get the error: Could not authenticate with the IBM Bluemix service. Please validate your credentials (also below).  Please can anyone help?

Something went wrong in the Build a Lemonade Stand App project, so I deleted the dashboard and reports and started this section again.  However, I'm not able to call a report "Order Total by Flavor", as is required for the task, as the system notes that this name has been used previously - I had to call it "Order Total by Flavour".  As as result I can't complete the task, as when I attempt to verify the step, the system can't detect the "Order Total by Flavor" report.  Is it possible to reset this part of the project or even reset the whole project to start again?  Thank you.
