I only have one user profile with admin priviledges. I can not login to it, I get the "user profile cannot be opened..." msg. I can boot into all Safe Modes. After reading some online support messages, I booted in safe mode and logged into "admin" profile and it says "loading default profile" and then logs me in. I then attempt to go to User Accounts and "Add a new User" to add a new user with Admin priviledges, but this option is Not Shown to me. If I try to click on "manage user accounts" it does nothing. It shows a microsoft "shield" on left side of this option. I know I can access my documents in safe mode still, but need to create a new user to move them to. HELP!
