So my laptop updated itself to the new Windows 10 Creators package, which I quickly rolled back from. However, ArcGIS thinks that my system clock was set back more than 24hrs. I uninstalled and reinstalled 10.4.1 (I had another code) but it STILL comes up with that error. I don't know what to do. Any help would be immensely appreciated!
I would suggest you to contact your Esri Tech Support representative.
ArcGIS License Manager might have detected the system date change and thus causing issues. It is usually done to prevent users from using the license beyond the defined period.

Thank you for the speedy reply! I've tried to contact them but they're only available Mon-Fri, 5am-5pm. I've tried completely uninstalling it (going through registry, all temp files, etc...) and I'm still having that issue. I've tried the recommendations from the link you sent (which was pretty interesting, I did not know there were that many processes governing the clock) but to no avail.
