[VuFind-General] View Record Problem

[<dn...@ny...>]

Hi
when I try to view the record, I receive this error

Warning: require_once(File/MARC.php) [function.require-once]: failed to open stream: No such file or directory in D:\wamp\vufind\web\services\Record\Record.php on line 23


what is it?
I never found MARC.php file even in a working server.
Thanks
kun
