They ask for everything back, just put everything back in the box and exchange for a whole new set. Also, I used it about 100 times consecutively farming ore and arrows from the guardian amiibo. When it stopped working the switch couldn't read it and the powersaves writer couldn't detect it either, it still lit up and worked fine but the powertag just stopped working completely. I'm on my third one now and it works fine even though I used it at least 100 times so far, but I stopped "farming" very fast, only use it for things I need. Also I noticed it felt a little warm to the touch when the first one stopped working, not sure if its from my hands handling it alot or if the tag itself was getting warm.
No problem, your program works as intended and does it well. It would probably be a lot better with the N2Elite since it can store like 100 amiibos at once so it wouldn't need to overwrite the data over and over again. I'm new to amiibos in general, but is there a way to modify the bin file to get the loot you want every time? Or is it randomized in game and the amiibo has no control over it?

Well the program generates a different modified file every time you use it, so if you generate 10 modified files of the same amiibo, you can use all 10 in game consecutively without changing the date in the system settings. With the powertag you need to use each file one by one, so using the powersaves software you write one modified file to it, use it in game, then write another one, use it in game and so on.
