There are only two reasons that the game didn't save
1. That you haven't unpacked the game and are playing from inside the rar file.
2. You have unpacked the game in a place where you don't have permissions, so the game can't create a save file.
If it's the first you will need to unpack the game I recommend using this
You must be registered to see the links
and unpack the game to your desktop. Then go here
You must be registered to see the links
and you may find a save close to where you where
If it's the second, move the main game folder to your desktop, start a new game go through the tutorial and once you get access to your phone load the autosave and that should be close to where you left off then create a new save
