Can't upgrade db: Admin Password Required- but won't accept my password

[doitwithlife]

Looks like I'm seeing the same or similar issue. When attempting a database update from 1.5.1 to 1.5.2 + 1.5.3 I'm getting this in the logs

[20-Jul-2014 19:40:49 America/Los_Angeles] PHP Warning: require_once(C:/Web/../includes/classes/vendors/password_compat-master/lib/password.php): failed to open stream: No such file or directory in C:\Web\includes\classes\class.zcPassword.php on line 52
[20-Jul-2014 19:40:49 America/Los_Angeles] PHP Fatal error: require_once(): Failed opening required 'C:/Web/../includes/classes/vendors/password_compat-master/lib/password.php' (include_path='.;C:\php\pear') in C:\Web\includes\classes\class.zcPassword.php on line 52


I'm working on a local version of my site (laptop running windows 8 . 1.5.1 was working fine. Did the file merge and the site appears to function, but tells me the database is behind. When running the zc_install database only option, when clicking upgrade now, it goes to a general error, 500 if my memory is correct.

PHP Version = 5.4.24, running on Windows 8 localhost

Anything to check next?
