Quoted from LTG:
I would play it a bit. To be sure all working. Then update it. That way if something isn't working. You know it was fine before the update.
And when you update the game. Follow carefully the instructions on the website. jerseyjackpinball.com - Support - Downloads - Hobbit. The only thing available is the 3.10 Full Install.

And definitely don't restart your PC with the update loaded, it'll start rewriting your computer!
Also, you might want to look into changing the motherboards battery. It's a typical car fob, 2032 style battery. PM me if you want tips, I just did mine a couple days back.
