The problem may be that, having reinstalled Windows you have created new users. They may have the same readable names as before, but Windows identifies a user not by name but by SID (security identifier) which is unique numbers that looks like: S-1-5-21-1180699209-877415012-3182924384-500
This means that a user named "John" on one Windows setup is totally different from a user named "John" on another one. Anyway, it's worth a try with one file to see if it solves the problem.
