Back when my mom asked me to write another post, I really didn't think I had all that much more to say. There were a couple of things that I thought deserved to be mentioned, so here it all comes.
I'm pretty sure that it was the same day that I was asked to do another post, that I turned on the computer and found this.
That little "Sign out now" button was completely useless. It let me log back in, but came up with the same error. I had to power the computer off, by holding the power button for a few seconds, and restart it to get it to start up properly. It has not happened again, but I don't have any idea what prompted it that one time.
