CourseMS script not working

HI
I am hosted on a windows 2003 server enterprise platform, with php 5.2.5 and mysql 5.0.45 installed. I have installed coursems script from https://sourceforge.net/projects/coursems in http://www.des-us.com/erp/coursems. The url I use is http://erp.des-us.com/coursems/admin/
On trying to log onto the admin section, I get this error:
Fatal error: require() [function.require]: Failed opening required ‘/home/users/web/b1582/whl.juzar/erp/coursems/admin/functions/database.php’ (include_path=‘.;c:\php\5\pear’) in \\boswinfs04\home\users\web\b1582\whl.juzar\erp\coursems\admin\includes\application_top.php on line 14
My cofig file is:



//CourseMS Paths

	define('HTTP_SERVER', 'http://erp.des-us.com/coursems/');
	define('HTTP_PATH', '/home/users/web/b1582/whl.juzar/erp/coursems/admin/');
	define('EXPORT_PATH', '/home/users/web/b1582/whl.juzar/exports/');
	define('REL_EXPORT_PATH', 'exports/');

and admin config file is:



//CourseMS Paths

	define('HTTP_SERVER', 'http://erp.des-us.com/coursems/admin/');
	define('HTTP_PATH', '/home/users/web/b1582/whl.juzar/erp/coursems/admin/');
	define('EXPORT_PATH', '/home/users/web/b1582/whl.juzar/exports/');
	define('REL_EXPORT_PATH', 'exports/');

Please check the site at http://erp.des-us.com/coursems/admin/, and let me know if somebody can help me out.
If help is not possible for this issue, then can someone please recommend or suggest any other course registration system?
thanks:confused:
