Yes you do not receive an email for each new update release. If you want an email to know the game updated subscribe to this topic:viewtopic.php?f=20&t=1420
At the very bottom you will see it.. and supermalparit will usually make a post to make it send us all an email letting us know.
To get the update you then have to re-download it from the email you first received to.. I suggest backing this email up *once thye help you recover it by doing what silverwarior said to do) - to make sure you do not lose the links again for when/if your wife deletes it.
