Anti-Splog api code not working

I keep attempting to enter my wpmudev api key for the anti-splog plugin (which is not showing up as a plugin on this drop down even though it was downloaded and installed.) After pasting in the api code from my membership i receive this message:

There was a problem connecting to the API server. Please try again later.
