Can't play ,"there was an error retrieving your currency balances"

Like title says, I'm getting a frozen screen with the message, " there was an error retrieving your currency balances". No idea why I'm getting this error, I bought the game when it came out last summer. Been playing it in dynasty mode for a year now. When this pops up I can't do anything, can't even change game modes. Really annoying, can't play the game I bought and no one to contact for help. Why is it so hard to just play a game you bought.
