Go into your your 'Settings' then to 'Date & Time, from there uncheck "Automatic date & time' and from there change the 'Set Date' two weeks forward (from today it will be 11/18/13) and then try to check for updates, and from there you should be able to receive the message that an update is available.
Good Luck!
