A DX camera, (D3100) can use an FX lens fine, but if the lens has no focus motor (AF-S) then focusing will be manual only.
Aperture setting will also not be communicated to a D3100 because there is no pin on the lens chip. Instead it uses what is known as an aperture index tab - and a D3100 has no aperture index ring to connect with the tab and tell the camera what the aperture is.
If you lock the aperture on the lens to its smallest setting, and thats F/22 or f/32 most likely, then the lens should not display an error message, but work on the camera with manual focusing - auto ISO will function as will shutter priority mode.
The part about an "un-authorized" card - well, she may have meant UN-TESTED card, Nikon tests several cards, and thats all they list.
I use untested by Nikon cards in my D7100 and have had no errors like you are seeing. Currently I am using a Samsung Pro & a Transcend card and have several cheap unnamed cards as spares that all work without error.

No her words were un-authorized. I did put the camera on manual, but no luck there.
