Trying to install the security patch SUPEE-9767 onto M1 EE v1.13.1.0 and i'm receiving the following error:

> 
> Hunk #1 FAILED at 225. 1 out of 1 hunk FAILED -- saving rejects to
>  file
>  app/design/frontend/enterprise/default/template/persistent/checkout/onepage/billing.phtml.rej
> 
> 
> 

I've checked the line in file indicated in the error and here is the related block of code:

```
<div class="input-box">   <!--(this is line 255)-->
<input type="password" name="billing[confirm_password]" title="<?php echo 
$this->__('Confirm Password') ?>" id="billing:confirm_password" 
class="input-text required-entry validate-cpassword" />
</div>

```

Any help would be appreciated.
