[Win10] No matter what I try, launcher does not remember Square Enix ID
So, I recently had to do some shuffling of my user accounts on my PC, and since then, the launcher does not remember my Square Enix ID, even if I tick the box.
I have gone through a number of suggestions, mostly revolving around security settings in Internet Explorer, but despite adding square-enix.com to my trusted sites, and dropping my security settings right down, I still am having no luck.
I have verified that temporary internet files are being saved, but for some reason not my username. Does anyone know how I might resolve this?
Alternatively, if not, providing me with a file I could place in the temporary internet folders myself in order to trick the launcher into remembering my ID.
Thanks!
