Not sure... where do I update the game? Sorry I'm a noob XD
The vita itself got the newest software version.
When you click the game bubble from the menu. Before you start the game there is sometimes an organ fish yellow icon with a down arrow in it. That's the update button. It's only there if there's something to download.
I would try seeing if the trophies are available in offline mode. Go to trophy page and click on ps vita instead of psn. If they are there try resyncing. If not you may have to reinstall the game.
Note that in the future it is always wise to save when you are going to let the system sleep or if you have to step away for a while. This way you can use the saves as a backup should issues like this arise.
