Using fitness, fitsharp and slim with C #

I am currently going through a tutorial on using fitness with C # here http://schuchert.wikispaces.com/FitNesse.Tutorials.0.CSharp I am currently stuck as my code / his code doesn’t work like was predicted. I do not have enough knowledge in this program to successfully figure it out. My code for the page:

!define TEST_SYSTEM {slim}
!define TEST_RUNNER {c:\Projects\fitsharp\Runner.exe}
!define COMMAND_PATTERN {%m -r fitnesse.slim.Runner, c:\Projects\fitsharp\fitsharp.dll %p}

!path c:\Projects\C_Sharp\Digital Video Recorder\Digital Video Recorder\bin\Debug\Digital Video Recorder.dll

!define COLLAPSE_SETUP {true}
!define COLLAPSE_TEARDOWN {true}

!|import|
|Digital Video Recorder|

!|Create Programs                                        |
|Name |Channel|DayOfWeek|TimeOfDay|DurationInMinutes|id? |
|House|4      |Monday   |19:00    |60               |$ID=|

      

        
        
        
      

    

where paths for dlls are definitely paths. But when I test this, an exception is thrown:

System.ArgumentException: String cannot have zero length.
   at System.Reflection.Assembly._nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, Assembly locationHint, StackCrawlMark& stackMark, Boolean throwOnFileNotFound, Boolean forIntrospection)
   at System.Reflection.Assembly.InternalLoad(AssemblyName assemblyRef, Evidence assemblySecurity, StackCrawlMark& stackMark, Boolean forIntrospection)
   at System.Reflection.Assembly.LoadFrom(String assemblyFile)
   at fitSharp.Machine.Engine.CurrentDomain.LoadAssembly(String assemblyPath)
   at fitSharp.Machine.Engine.ApplicationUnderTest.Assemblies.AddAssembly(String assemblyName)
   at fitSharp.Machine.Application.Shell.Execute()
   at fitSharp.Machine.Application.Shell.Run(IList`1 commandLineArguments)

      

        
        
        
      

    

I have been doing this for a while, but I cannot get it to work
