problem with PHP installation

I have a problem with a PHP installation. Every time I try to open a script it seems to be missing some libraries. Can someone help? Here is one of these error messages: Warning: main(./libraries/grab_globals.lib.php) [<http://www.php.net/function.main>function.main]: failed to create stream: No such file or directory in c:\phpmyadmin-2.5.0\index.php on line 9 Fatal error: main() [<http://www.php.net/function.main>function.main]: Failed opening required './libraries/grab_globals.lib.php' (include_path='.:/php/includes:/phpbb2/includes:/phpmyadmin-2.5.0/libraries') in c:\phpmyadmin-2.5.0\index.php on line 9 Nils Puhlmann <npuhlmann@westbay.net> - Certified Information Systems Security Professional (CISSP), Certified Novell Instructor (CNI), Microsoft Certified Trainer (MCT), Netscape/Iplanet Solution Expert, Cisco Certified Network Associate (CCNA), Check Point Certified Security Engineer (CCSE Firewall-1) - *************************************************************************** The information in this email and in any attachments is confidential and intended solely for the attention and use of the named addressee(s).
