Thanks to Sean at http://www.limeleaf.co.uk we actually resolved this by adding the mime types. See this code snippet:

$wpbb_allowed_mime_types = apply_filters(
				'wpbb_application_allowed_file_types',
				array(
					'application/pdf',
					'application/msword',
					'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
					'application/vnd.openxmlformats-officedocument.wordprocessingml.template'
				)
			);

			/* check uploaded file is in allowed mime types array */
			if( ! in_array( $wpbb_filetype[ 'type' ], $wpbb_allowed_mime_types) ) {

				/* upload file not allowed - add to messages */
				$wpbb_messages[] = '<p class="message error">Error: CV is not an allowed file type.</p>';
				return; //this return statement added by Lime Leaf on 17/7/2015 to stop the form submitting when the incorrect file type is added
			}
