If this is a new install then what do you mean by "Copied over the other files".
If this is a clean install there are no files to copy over.
If all your doing is a reinstall of windows there is no such thing as a brand new registry if windows is being reinstalled into the same directory. A true clean install of windows means that the hard drive has been cleaned and wiped by a reformatting of the drive then an install.
Anything less means your installing to the same registry and files from the old one will remain there and cause issues.
Did you reformat the drive before installation?
Did you previously have windows 7 as your OS or is this an upgrade from an older OS and not a clean installation?
If this is an upgrade(not a true install) is the game being installed on a separate drive or at least into a directory not PROGRAM FILES?
================================================
I would also have a read at these threads for other information concerning installation. It may provide you with clues to your issue.
