Is the google API messed up today? The ranking thing only checked about 1/2 my keywords; and when I tried a few manually it said that I've run out of queries (but I never get near my 1000 limit anymore) and when I check a few myself, they show up as N/A, but when I search google, they are right where they should be.
Maybe Google didn't reset the daily limits on your key today yet and you used most of the queries yesterday or something.
i had this same problem - i only use my api key for about 30 keyphrases and 6 sites in the ad network. just an FYI.
