You're trying to make a subclass of a class that no longer exists. There 
recent changes in the Morphic hierarchy were discussed in this mail 
list. Please find and read those messages.

Alternatively, you can use the system itself, explore it, and see what 
new classes replace those no longer available.

Happy explorations!
