i suppose the UPLOAD class has some problems in it
the simplest way is to reset the file_name var:
Code:
foreach($_FILES as $key => $value)
        {
        $this->upload->file_name = '';//insert this line
        if(!$this->upload->do_upload($key)) echo $this->upload->display_errors();

or

Have a look at this topic for a solution: File extension problem with upload
