@reporter: Please feel free to subscribe to our the Agilo google group where we handle all Agilo related support. For more details please see AgiloForScrum.

Please make sure your sprint has a valid start and end date or duration (e.g. set them in the administration panel). Some sprints with invalid date fields may cause the backlog to display this error. We are tracking this ​https://dev.agile42.com/ticket/1069issue and it will be fixed in the upcoming release.
