Anti Splog won't accept my API key

I tried to install Anti Splog and it told me to register my API on your site, so fine, I did that and put the API in but it won’t accept it, says “There was a problem with the API key you entered: “Your Multisite Domain is not yet registered for this API Key. You are attempting to connect from Fix it here” But when I go “here” (to your site) and attempt to register the domain again, it says that domain is already registered!

However I have just been reading some of the posts about this plugin and see that Gabe had a problem with it breaking custom post types, I had this same problem with the Blogs Directory plugin with no solution, so maybe I won’t be able to use this plugin anyways.
