Anti Splog plugin keeps giving me error with API key.

Here is the error I get
"There was a problem with the API key you entered: "Your server IP and WPMU Site Domain is not yet registered for this API Key. You are attempting to connect from 174.120.188.2." Fix it here»"

I then go to that page, get my API key, add fightlogs.com along with the ip given above to the registered WPMU servers, then go to the main page to add in teh api key, and it keeps giving me this same error.

What am I doing wrong here? Thanks!
