Anit-splog: API Key doesn't verify

Installed Anti-splog latest version (1.0.7) on WP3.1 with Multisite on.
Obtained an API Key, but when entered in the Anti-splog settings it doesn't verify.
I have tried both the IP address and the domain name, but no luck.
Error message:
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 sitespec.com."

Now the only weird thing I see is at the API registration page my domain is listed as: itespec.com (so a missing 's'). Tried deleting and re-entering but no luck.

Any ideas?
