I didn't get any response until late February 2023, when he sent me a link that produced a 404 error. I complained about that, and about a week later, I got an email from him that asked me whether I'd been able to download that archive he'd sent me the link for "in late January".

I told him, again, that the link he'd sent in February hadn't worked, and that I'd told him that, and in a couple of hours everything was wrapped up satisfactorily.

Had he been able to do that when I'd asked for it five months earlier, I would undoubtedly have a much higher opinion of the man.
