Server down?

All day all I've gotten is "Communicating, please try later." What gives?

Have you checked your Internet connection? you might just have low range or something.

I get this a lot restart your iphone/whatever you use and it works

This has happened to me before as well. Sometimes it works when I do what Link says, but if you are using an Ipod, just delete the app and redownload if it doesn't work.
