I allowed a Windows Update to run on the server hosting SQL Server 2014. When I tried to run the MDS Configuration Manager, I got "This database requires an upgrade. You cannot change system settings until the database is upgraded." I clicked the Upgrade Database and got this exception:
Microsoft.MasterDataServices.Configuration.ConfigurationException: Column names in each view or function must be unique. Column name 'VersionNumber' in view or function 'EntityHistory' is specified more than once. ---> System.Data.SqlClient.SqlException:
Column names in each view or function must be unique. Column name 'VersionNumber' in view or function 'EntityHistory' is specified more than once.

"EntityHistory" is an entity I created with MDS Configuration Manager before the Windows Update occurred.
I have a series of SSIS packages that continue to load data into the database, so it appears to be ok.
I have no idea what to do now. Please help.
