The Energon Pub

okay so i recently got revenge of the fallen for ps3 but when i sign in there is a notification that there s a new update for it. I go ahead and start downloading the update and it gets to 1 percent complete.meanwhile up in the corner where it says how much time remaining in the download,it keeps racking up more and more time.then it went from 4 minutes to about 100+ minutes in about a period of 2 minutes.plus the download completion doesnt move an inch.

Any one got any ideas to help me out?

turn off your system.
check your internet connection.
turn on your system.
check to see if there is a system update.
run the connection test.
try again.
