App blocked with Google tasks

Hi,

I'm trying to get stuff set up with Google tasks, but I'm getting an error when I try to add the web service in autoweb, "This app is blocked. This app tried to access sensitive info in your Google Account. To keep your account safe, Google blocked this access"

I've seen some people having the same problem with other Google stuff, but haven't found a fix for Tasks. Is there anything I can do?
