When I hit OK after entering the locations of SAM & SYSTEM it yields an error message that states:
Error while opening key HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\COntrol\Lsa
The system cannot find the path specified.
The rest of the path to the error couldn't be shown in the small dialog box. The only path I found in that LSA registry entry was a %SystemRoot%\system32\ntmarta.dll and that file looks pretty intact to me.
