Hi I just signed up for the Google Base API Key (For installed applications), I was provided a key, which I copy/pasted into Keyword Tracker Tool sign up page (as requested) and everything looked fine until I tried to add a Keyword !! when I got this error message :- "The request returned the following error: Exception from service object: Invalid authorization key:" Help please , don't know what i did wrong ? Definately copied/pasted the EXACT code into the signup. Anyone have any ideas ? Thanks
