Hope you were able to work it out, one way or another, Roxie.
But honestly, in my view, I think you dodged a bullet. Upgrading an operating system just plain does not always go well. You could get it to go through and then find that some of your softwares or programs just won't operate properly - there are so many things that can cause incompatibility.
If you, then, decided to go back that can cause so many additional problems. It's definitely a crapshoot.
That doesn't even approach the scenario of all the bugs that have not yet been worked out of the new operating system. I'm not one to jump into something that big right away. I feel very comfortable waiting it out, but YMMV and I get that too.
