I really really hope that someone can help me with this.

After downloading and installing the current versions of SS, ecommerce, payment and payment_payPal mods, and configuring, all seems fine until PayPal attempts to return me to my website (either after payment is made or aborted), then I this error:

[User Error] singleton() Called without a class
GET /fstest/PaypalExpressCheckoutaPayment_Handler/cancel?token=EC-37W42336T7825260H Line 343 in /Applications/MAMP/htdocs/fstest/sapphire/core/Core.php

After I highlighted this, a fix was posted to payment (https://github.com/burnbright/silverstripe-payment/commit/6ab0e8b349d2c1f92c014309cedf1916c145b501) which corrected the earlier problem and allowed visitors to return to the website after PayPal.

However, I now have a new problem: in the CMS, clicking the "Store" tab produces this:

[User Error] Uncaught Exception: Unable to traverse to related object field [PaymentMethod] on [Payment]

This is happening on my store which is otherwise ready to go live now, but I've been able to replicate this problem on a completely fresh install. Can anybody please help? Many thanks.
