I looked up your account and didn't know your meta user name, but I did find the cohort called "RELPE 2015".  That looks like it had some kind of problem validating.  Do you see a button "Validate Again" when you open up that cohort?  If you do, try clicking it and confirming the message.  It should tell you after some pause that it started validating and give you a Refresh button.  You can click that and let us know what you see.  If you see FAILURE, let me know the time that happened so I can look it up in the logs.  Thanks for the report Anna.
