How do I clear out Tombot's brains/AIML files?

[Gutspiller]

I went scouring the web for new aiml files and I guess when I uploaded some that I found, instead of adding to his brain, they overwrite what I had and cleared him back so now his really stupid and almost always responds with:

"I didn't understand that, Gutspiller. You have to understand that I'm just an example bot. I didn't understand that, my lord. I know how to handle about 151 inputs, this one isn't one of them."

Can somebody please help me on how to either put him back the way he was or clear all his brains and insert the original decent ones so he isn't SOO dumb? I really need to know how to do this.

Please help.
