You can certainly kindly let them know that this isn’t really gonna work and explain why (and let them know you appreciate the effort), but the rest of it is way overkill and could easily be seen as patronizing, imo.

If the goal is to get them to load it correctly, the way the top level poster describe is far more likely to be successful than this. Once someone feels attacked, and telling them ‘you’re doing it wrong’ is most likely to be received as an attack, they go into a defensive mode and will become mostly unreceptive to any further suggestions from you because they will be too busy trying to defend themselves.
