TFS 2010 "The Iteration dates are not valid" error after upgrade to SQL 2008 R2

After upgrading SQL Server Analysis Services 2008 hosting TFS 2010 to SQL Analysis Services 2008 R2, users cannot refresh the Burndown chart in an Agile project workbook. They receive the following error:

After saving the updated msmdsrv.ini file you will need to restart SQL Server Analysis Services for these changes to take effect.
