Password Encryption

I am trying to follow the tutorial movies for password encryption. I am using SA ver 1.1.9 and am using the archived movie set. The steps seem simple to follow and my changes seem to correspond with the instructions, yet after 5 tries now, I keep getting the following error messages for my login page:

Warning: require_once(../WA_SecurityAssist/WA_SHA1Encryption.php) [function.require-once]: failed to open stream: No such file or directory in C:\xampp\htdocs\guitar-tables\contman\Admin_LogIn.php on line 1

Fatal error: require_once() [function.require]: Failed opening required '../WA_SecurityAssist/WA_SHA1Encryption.php' (include_path='.;C:\xampp\php\PEAR') in C:\xampp\htdocs\guitar-tables\contman\Admin_LogIn.php on line 1


I have similar errors on the other pages (registration, etc.) These pages were functioning fine prior to my encryption attempts. I do not see the file, WA_SHA1Encryption.php, in my WA_SecurityAssist subdirectory and yet it is "required_once" on all the affected pages. Is it supposed to be created while going through the encryption process? If so, I have not seen it after any of my tries. Again, I'm at a total loss as to what I am doing wrong. I feel like I am never going to get through this process. And I still have several steps to go.

Thank you.
