PRO Plugin Stopped Working

After latest WOOCOMMERCE updates the PRO version of the plugin is broken.It had been working fine. Now, however, both global and single product gift configurations don’t work. Specifically, once a gift gets auto added to the cart it does not remove if the criteria item is deleted from the cart. Secondly, the ‘greater than’ and other quantity settings don’t calculate properly thus allowing a gift to be added when the criteria hasn’t been met and/or prior to it being met. I’ve tested many variations for getting this to work again and they’re all buggy in one way or another. As I said, it had been working fine for a few weeks without problem.

Also, are there not automatic updates for the plugin? — how are updates handled then? I don’t see how to LOG IN to the PRO site that we are referred to. This is a premium paid for plugin — please advise.
