We're now on 3.1.22. You could wait until it comes through automatically.
It's painful, but the best way to learn is to suffer and practice recovery. When it's happened a few times, you'll learn not to panic and to stay in control without having to revert to Hosting each time. But I've needed help from my Host today so it never goes away.
I suggest you bite the bullet and try it. There's not a lot we can do to help until there's a problem to diagnose.
Good luck!
