Sharparchitecture upgrade from 1.5 to 1.9 error

I have upgraded SharpArchitecture from 1.5 to 1.9.

I have followed the guide here http://blog.sharparchitecture.net/post/Sharp-Architecture-19-released.aspx, and ensured that I have set "copy local = true" for the various DLLs, but I still receive the following error when running the site:

Exception Details: System.ArrayTypeMismatchException: Attempted to
access an element as a type incompatible with the array.

Source Error:

Does anyone knwo what I might have forgotten?

I have been looking at the versions of SharpArchitecture in the different project several times, but apparently I had missed one project which didn't have the SharpArch DLL set to Specific Version.
