I need the original class_core.php file

[djdonx]

I installed a hack that went wrong and I need the original class_core.php

Where can I get it?

Needed asap

Fatal error: Call to undefined method vB_Database::execute_query() in /mounted-storage/home51c/sub009/sc35296-LGXB/www/forum/includes/class_core.php on line 410

Code:
*/ function query_read($sql, $buffered = true)
{
$this->sql =& $sql;
return $this->execute_query($buffered, $this->connection_master);
}

EDIT: Doesn't matter anymore. Fixed it
