No problem tgrimes
I doubt that the kit will have instructions, but someone here will walk you through the procedure.
Lens changes are part of life, and so is dealing with the dust when happens.
There is a chance that your camera even had that spot right from the factory.
You just learn what to look for, and how to deal with it at the time.
Try not to change the lens in dusty conditions.
Point the camera upside down when changing them.
Loosen the rear lens cap on the new lens first, so your not fiddling with it without a lens on your camera.
Keep your camera bag clean inside and out, plus blow off your lenses from time to time.
Just little things like that will help keep the sensor clean, but they still won't eliminate the problem.
I could have fixed your image with my software as well, but never thought of it at the time.
