I have seen some really dumb things on the Internet but yours are the dumbest.
If you can find that anywhere, show us a link.

Any way on a Nikon D7100 and with any AF lenses or even MF lenses that have CPU it should display the same range of aperture as the lens. No crop factor whatsoever. With non CPU lens you will have to enter the maximum aperture of the lens in the camera for it to display correctly.

OK So everybody has an opinion. We're talkin MF lenses used in manual, AF lenses give an error soon as you take them off the smallest f stop. I've tested 50mm f1.4, 50mmk f1.8, 50mm f2.0, 28mm f2.8, 200mm f4.0 and 300mm f4.5. Tested on D7100, 2 D7000, D300s, D300 and D200. Every lens on every camera has read a lower f stop in the viewfinder, so its not the lens and its not the camera

You are referring to the FEE error message displayed on DSLR camera LCD. It is explained in your camera's manual.
The fEE error is commonly the first error message in the manual's list.
This is known to anyone who has used an old lens on a newer Nikon camera, film or digital, full frame or crop, with an EE servo coupling.
If the "experts" you spoke with at Nikon were not aware of this then they are not very knowledgeable and don't belong on the help line staff.
You are right about one thing. It's not the lens and its not the camera. It's your own fault for not reading the manual.
If you don't have a manual for your camera you can download a copy for free. It's easier to use than the paper version that came with the camera.

Again you need a better question.
Per your description you face two possibilities. Either the pix did NOT download to the PC, or the target Location of the download was not known to you and youre always looking in the wrong place to find pix files for posting.
Its your system and youll hafta comb thru it. The UHH clown car will post all the guesses they can think up. Some will be nonsense and some might make sense yet not match your situation. If someone somehow does hit the nail on the head, good luck realizing it amidst all the noise. IOW youre back to combing thru your system, not just to find files that may or may not exist, but also to get to know all your settings and defaults (incuding the targets of downloads from apps).
For a ghost of a chance, youll need much clearer questions and descriptions than what youve been posting.

If you want to have the aperture displayed correctly with MF lenses you have to enter the lens data for each of the lens you use. It's in the NON CPU LENS DATA menu. You can enter the data for up to 9 lenses. Whenever you mount the lens you will have to select the lens number. This is not only for the camera to display the correct aperture in the viewfinder but also to get the Matrix Metering to work correctly.

This has been mentioned, but might have been missed.
"AF lenses give an error soon as you take them off the smallest f stop."
Shot in the dark ...
If you are changing the aperture by changing it on the lens, that could be the issue. F stops on these cameras need to be set on the body, not the lens.
