Check it out. All you have to do is remove the faceplate, set the bobbin in so the hook part is up, and put the faceplate back on. That fixes it!
Good luck!
I'm sure you meant the needle plate, which goes under the needle.
The face plate is on the top left facing side of the machine.
A lot of these names are very similar and easy to mix up.
