Dialogue Plugin

Could someone please help me out here? I can’t get anything, even the base demo of the dialogue system, to work. The documentation is very sparse and vague about some things, so I have no clue how to set anything up. I can make and understand the dialogue trees just fine, but for the life of me can’t get any of the plugin to function in-game. I’ve tried creating my own widgets using the guide, but there’s no “To NPC Reply” node available to me, and no explanation on how to make one. Basically, I feel like I just wasted a lot of money on something that looks awesome, but is essentially unusable. If there’s any way I could get some actual pointers or could request a refund, that would be much appreciated.

Cheers
