I'm glad you like it! And of course, I'd be happy to help troubleshoot.
First, it's worth forgetting the authentication and setting it up again just in case it timed out during testing, etc.
if that doesn't work, double check that you have the word entered correctly, and that you have the box in Settings to spawn on a keyword checked. Also, that there's at least one item in the keywords category for spawning.
I none of those fixes help, I'd need to see a log file to get a better idea of what's going on. (You're free to send one via my Gmail address or on Twitter.)
