Make sure that you have created the Info and Controller classes objects using the New keyword.

Because the Update method uses these both classes and initialization is required for both these class objects.

Unless you are extending DNN you really do not need the source version.  Try using the install version.  Vladan Strigo and Michael Washington both offer excellent tutorials for getting started.
