ahaone on "[Plugin: PayPal for WooCommerce] PayPal Express Do not complete the checkout process!"

Hi there,

This is the result:
http://openvintageshutters.com/?wc-api=WC_Gateway_PayPal_Express_AngellEYE&pp_action=expresscheckout
http://openvintageshutters.com/?wc-api=WC_Gateway_PayPal_Express_AngellEYE&pp_action=expresscheckout&use_bml=true
Using Sandbox account. (which work successful with built in PP checkout in Woocommerce).
Using "Mystile" Woo Theme with default settings for compatibility. There are only Woocommerce and PP for Woocommerce plugins working.
Any idea how to solve this issue? Maybe I'm missing some checkmarks in woocommerce settings panel?

Your help is greatly appreciated!
