Myself and others have received a warning said that the games license expired. When this happens Google Chrome shuts down the page entirely and will not allow play. I found I still get the warning with Internet Explorer but it allows me to continue to play the game. And for time reference about 11:30a.m CST for me.
Kindness is more important than wisdom, and the recognition of this
is the beginning of wisdom. –Theodore Issac Rubin
