I'll add this because it has happened to me - sometimes you're in all in one mode and you still don't see your code, just the file name that you selected at the top of the window - this is because there is a horizontal divider that is pulled all the way to the bottom of the window. Look for 1 little dot at the bottom of the window in the center, if you drag that up you'll be able to see your code again.
