Customer View & Print Invoice - error

[cypherja]

I downloaded and installed Customer View & Print Invoice at Checkout Succes.

 

Everything seems to work until I click the button to bring up the invoice for the customer to print, and I get this error:

 

Warning: require(admin/includes/languages/english/invoice.php) [function.require]: failed to open stream: No such file or directory in /home/cyphersg/public_html/catalog/invoice.php on line 28

 

Warning: require(admin/includes/languages/english/invoice.php) [function.require]: failed to open stream: No such file or directory in /home/cyphersg/public_html/catalog/invoice.php on line 28

 

Fatal error: require() [function.require]: Failed opening required 'admin/includes/languages/english/invoice.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/cyphersg/public_html/catalog/invoice.php on line 28

 

I know it's because in the catalog/invoice.php, line 28 says "require('admin/includes/languages/english/invoice.php');".

 

I didn't see any file in this package that was supposed to go there, and, obviously, there is no file by that name in that directory (hence the error).

 

Did I miss a step somewhere. Is the file missing in the package, or am I supposed to get it from some other place?

 

This is exactly what my client is looking for, so any help would be appreciated.

 

Thanks!!
