I am missing most of the game files. Help?

If you have multiple users on the computer, you will have to log onto the user that bought the game. I'm sure Steam installs one user per account.

By more than one user, do you mean more than one user of Steam, or more than one user on the actual computer itself. If you mean more than one user of Steam, I am logged in as myself. If you mean more than one user on the computer, I haven't checked that yet, but I think, since the folder is meant to be in the c drive, that the user wouldn't matter.
