The classic line: “Something came on, and I pushed it, and I didn’t read it, and now I don’t know what’s going on.”
What was going on in this case was a user dealing with Microsoft changing Hotmail to Outlook.com. He may have been a little less thrown if he’d read the message about the change.
When you see a message appear on your screen, read it. Think about writing it down, since you may not understand it, and after you click a button, you probably won’t remember what it said.
Whether you either (or neither) of these things, if you find yourself stuck, I’m happy to help get you unstuck.
