if you're using AIMLBot which I see that you are, it doesn't support duplicates... you can't just pickup a random aiml file of ALICE and expect it to work.
atleast that is what i encountered in my aiml responder.
I'm using AIMLBot with the french aiml files from Alice. There is no duplicates in those files, I checked myself. It was working correctly for 3 weeks and just broke recently with one of the lastest updates.
