NHL 14 app

[xxcoylexx3]

I insert the same exact username and password in my app as in my origin ID online, bu when I do it on the app, it doesn't let me log in. It says "Error. There was an issue with the network connection (500). This may be a result of server maintenance. Please refer to help.ea.com/nhl/nhl-2014 for more information." I went there and it didn't help. If someone could please help me by answering my question, than that would be great. Thanks.
