Easy-Custom-Post is visible in search, but 404 when clicked

Hi!
I’m new –

• I’ve installed ECP,
• created a custom post type: Attractions
• created an Attraction: (joes-cafe)
• created a category set: attraction-type (cafe)
• copied single.php to single-attractions.php
• added the category: cafe to wp-navigation-menu

But when I visit the menu item, I get a 404,
when i search for the cafe by name, i see an excerpt, but clicking its title gives me a 404!

Any Clues? What am i doing wrong?

I am using a Thematic child theme, and i duplicated single-attractions.php as single-attraction.php just in case, because i found the distinction confusing…

Thanks, Tim
