SimpleText example in FileTypeSupport Sample not working

I get a compile error in SimpleTextParser.  It appears that something has changed in the 2011 release.  It evidently needs to have the SetFileProperties method in order to meet the INativeContentCycleAware interface.

 So, I have added

         Sdl.FileTypeSupport.Framework.BilingualApi.IFileProperties _fileProperties=null;

        void INativeContentCycleAware.SetFileProperties(Sdl.FileTypeSupport.Framework.BilingualApi.IFileProperties properties)

        {

            _fileProperties = properties;

        }

I also added the if statement below:

        protected override void BeforeParsing()

        {

            // set progress reporter to the beginning

            OnProgress(0);

             // open the native input file for reading

            if (_fileConversionProperties != null) // DWH use the one that got set

                _reader = new StreamReader(_fileConversionProperties.OriginalFilePath);

            else

                _reader = new StreamReader(_fileProperties.FileConversionProperties.OriginalFilePath);

        }

 Then when I try to open the simple.text test file that is supplied in the sample, when I am doing the Prepare batch process, I get an error in the Convert to Translatable Format step:

 

I would appreciate any suggestions.
