Flash update IV Game Hint
It means you need to get off Chief Delphi and check your e-mail 
My personal theory is that the next hint (or something relevant) will be released at 8:30 Eastern time. The last line of that song is “We only have 14 hours to save the Earth!” 8:30 is 14 hours prior to 10:30, the beginning of the video stream.
Well, that’s my contribution.
