Google Checkout module for ZC 1.3.x (beta)

[lextechs]

I'm having a very difficult time with this module.

Using Zen Cart version 1.3.8
Module version 1.4.7

First, version 1.3.8 (as opposed to 1.3.8a) should work with 1.4.7, right?

My main problem is that no option for Google Checkout shows up when there are items in my cart, and I go to checkout. I'm pretty sure the template files are in the correct place.

In the admin, I have the module enabled.

I suppose my concise question is:
Even if something is configured wrong, but my tpl_* files are in the correct place, and the module shows up fine in the admin, shouldn't I AT LEAST get a greyed-out box on the checkout page?

Is there anything else that would cause the module to be totally absent in the cart?

I have asked that same question since the mod first came out and i remember getting a reply that GC was created to allow shoppers to purchase items without having to create a account and login it to the store. so if they use GC to check out there would be no need to have in on the payment page like with paypal and other payment mods. I am sure you can get it there but i wouldn't know how too.
