Plugin is updated for Woocommerce 2 now. So please try again!
Yes, i will update this so soon at possible.
Sorry for my inactivity.. Got a mail about this yesterday with information that my plugin was broken in woocommerce 2.0 will check this out right away.
Whats your woocommerce version?
I think i will drop feature support for woocommerce 1.xx and just focus on 2.0.
