This is part of the reason I hate dealing with our "tech" at my job. They do software upgrades on our digital projectors and things start going to crap. Templates that we've been using for the past year start having problems. Call the tech, his answer is "You're doing it wrong" Tell him I haven't changed anything in my process, and its not working. His response is "These things don't just suddenly stop working. You're doing it wrong". Have this happening over several days, other people using the templates and not working, so we all just suddenly got dumb I guess.
Finally our District manager gets involved and tells us to start doing it right, since he believes the tech when he blames us for everything that goes wrong. I write out a step-by-step guide of what we have been doing, send it to the district manager, to our tech, and to our techs boss. Tech is finally forced to come out and look at the problem in person, since all he had done prior was use a remote connection which told him everything worked. Turns out that the template that "we were doing it wrong", had gotten corrupted during the update and was missing some files. No apology, no I'm sorry, he just re-copies the files and we are back in business.
I hate the fucking guy, and dread whenever anything goes down that I cannot attempt to fix (don't have the computer passwords, or the keys, or anything dealing with electrical wiring). It always turns into 20 questions, which I have already tried and determined it is not that, before he comes in to address the problem. And when he does come in, it seems like 75% of the time he has no idea what the problem is either and has to call his supervisor to try and talk him through a fix.
