' Sequence contains no elements' exception when initializing ninject

I have a problem with Ninject which I have not seen before and don't know how to fix. I am using the MVC NuGet package for MVC 5. In my NinjectWebCommon.cs, there is the following method: ``` public static void Start() { DynamicModuleUtility.RegisterModule(typeof(OnePerRequestHttpModule)); DynamicModuleUtility.RegisterModule(typeof(NinjectHttpModule)); bootstrapper.Initialize(CreateKernel); } ``` However, it falls over when trying to execute the last line, complaining that the "sequence contains no elements". I was previously using Unity for DI but have changed to Ninject. Any ideas? Thanks in advance, M
