Jeff:

I actually just found myself having that same exact problem tonight as well. 
My error says:

"Event class should be a list..." 

...just the way you mention it for your score.  I'm not sure how to proceed,
but I just wanted to let you know that it's not just you.  And I too am not
very comfortable with Scheme.

I'm sure someone will help with this! :)
