Hi Richard,

After upgrading to CMS Import 2.5 (on an Umbraco 6.1.6 site), I'm getting a lot of error when starting the site. The error is as follows:

Method 'get_DataTypeId' in type 'CMSImport.Library.AdvancedSettingControls.BooleanSettingsControl' from assembly 'CMSImportLibrary, Version=2.5.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.

Stack trace:
