Bpost breaks woocommerce

I updated wordpress, woocommerce and bpost plugin and now I get the following error when I try to visit the checkout or even the settings page of woocommerce:

`Fatal error: Uncaught Error: Call to a member function is_wc_version_equal_or_greater_than() on null in /var/web/vd5227/public_html/wp-content/plugins/bpost-shipping/classes/class-wc-bpost-shipping-method.php:37 Stack trace: #0 /var/web/vd5227/public_html/wp-content/plugins/woocommerce/includes/class-wc-shipping.php(169): WC_BPost_Shipping_Method->__construct() #1 /var/web/vd5227/public_html/wp-content/plugins/woocommerce/includes/class-wc-shipping.php(149): WC_Shipping->register_shipping_method(‘WC_BPost_Shippi…’) #2 /var/web/vd5227/public_html/wp-content/plugins/woocommerce/includes/gateways/cod/class-wc-gateway-cod.php(55): WC_Shipping->load_shipping_methods() #3 /var/web/vd5227/public_html/wp-content/plugins/woocommerce/includes/gateways/cod/class-wc-gateway-cod.php(31): WC_Gateway_COD->init_form_fields() #4 /var/web/vd5227/public_html/wp-content/plugins/woocommerce/includes/class-wc-payment-gateways.php(105): WC_Gateway_COD->__construct() #5 /var/web/vd5227/public_html/wp-content/plugins/woocommerce/includes/class- in /var/web/vd5227/public_html/wp-content/plugins/bpost-shipping/classes/class-wc-bpost-shipping-method.php on line 37

Any idea on how to solve this?
