Na, it's not entirely on you, normally I am tech-savvy enough that I should have thought about re-installing earlier myself. Thanks for the info with the Gem of Illusions, I remember getting it and trying it out once, but I misunderstood its purpose and thought it was for previewing or browsing through costumes without having to equip them. As I didn't have many costumes at this point (just the maid) I didn't use it again and then forgot about having that item later.
