Thanks for stepping in guys. I got the database update to run, just by trying it a lot, with the higher timeout numbers in the php.ini. (changed from 30 to 300 seconds for those who are trouble shooting their own).
Now, I'm getting the "Fatal error: Uncaught exception 'Twig_Error_Loader' with message 'Unable to find template" message on my updated site and, when I try to install a new site using the same database, I can't seem to log in. Putting in my username and password just returns me to the log in screen with no error message. If I put in the wrong password, I DO get an error message so...not sure why it's taking the password but then returning me to the log in screen, un-logged-in.
