randon block errors

Hi I have gallery 1.5RC1 and php platinum7.6 and these are the errors when I set up the random block

Warning: main(D:\apachefriends\xampp\htdocs\blocks/init.php) [function.main]: failed to open stream: No such file or directory in D:\apachefriends\xampp\htdocs\blocks\block-random.php on line 45

Fatal error: main() [function.require]: Failed opening required 'D:\apachefriends\xampp\htdocs\blocks/init.php' (include_path='.;d:\apachefriends\xampp\php\pear\') in D:\apachefriends\xampp\htdocs\blocks\block-random.php on line 45

Could some one please help me out?

Thanks in advance.
