The Gotowp Woo addon was working, now is not ¯\_(ツ)_/¯

Hey,

The plugin had been working correctly but I am finding now that I can go through with a purchase but it never registers that person for the webinar and there is no join now button anymore. Yes, I do have virtual and downloadable selected. It has just stopped working the way that it was. My best guess as to why it stopped working is because Woocommerce has had a pretty significant update recently. Can you point me in the right direction? Thanks for your help.
