I don't have the slightest idea what is going on, help me!
I have a project due on Sunday for a motion graphics class. We need to use a JPG file in the project. I imported it into After Effects, and every time, this is what I end up with (see the screen shots, as I can not BEGIN to describe what the heck is going on here!)


I'm using AE CC 2015, 2015.2 release, Version 13.7.2.3
My computer is a MacBook Pro, macOS High Sierra Version 10.3.4
And I updated my computer last Sunday
I have not used this program before, so I don't know what I'm doing wrong. My professor already suggested to reset the preferences, which I've already done, and that didn't help at all.
