You can either contact Sinsiroad (send email to halak[at]sinsiroad[dot]com) and ask them to unlock the game for you if you've cloud-saved it, or wait until the last time you fast-forwarded to.

e.g. If you fast-forwarded the game to 03:00 PM, opened the game, closed the game, changed the clock to 01:00 PM, then reopened the game, you need to wait for 2 more hours for the game to unlock itself.
