After upgrading to 7.4.1 I am unable to Courier Media items.

The first error was that there was no column for help text, So I added this to both environments

ALTER TABLE cmsPropertyType ADD helpText NVARCHAR(1000) NULL

and now another exception is being thrown when packaging items.

Please can anyone help
