TV 'On Demand'

Hello, I am at work & I have for (years) "streamed" FOX-News on my work computer. Today, 04/23, when I went to log-in & selected FOX-News I received an error message that to be able to "watch "FOX-News" I would have to (upgrade) my package? How can this be, I've viewed this your years at work, all day long??? Please assist.
