Problems with API requests after upgrade

Hello,

We recently upgraded to plugin version 4.4.2, and after that we are seeing API errors in the back-end on the “order lines” (the payment status that it gets from Quickpay).

It seems like it are trying to lookup orders payed with Paypal and clearly QuickPay gives an error (404 response).

Thise are the lines in the log:

03-24-2016 @ 12:58:54 - QuickPay API Exception file: /var/www/default/wp-content/plugins/woocommerce-quickpay/classes/api/woocommerce-quickpay-api.php
03-24-2016 @ 12:58:54 - QuickPay API Exception line: 189
03-24-2016 @ 12:58:54 - QuickPay API Exception code: 400
03-24-2016 @ 12:58:54 - QuickPay API Exception message: id: is invalid<br />

03-24-2016 @ 12:58:54 - QuickPay API Exception Request URL: https://api.quickpay.net/payments/54529416WS8618432
03-24-2016 @ 12:58:54 - QuickPay API Exception Response DATA: {"message":"Validation error","errors":{"id":["is invalid"]},"error_code":null}

Any tips on how to stop this from happening?

Thanks in advance
Hans
