hello, I downloaded the latest version (1.1d), I created a new project (my version of Godot is 3.2.3), I put the folder of "addons" in the folder where this new project is saved, and everything works fine, I do not give any error. The script in "custom_dialogue_node.gd" is fine, has no error. Maybe you have to open godot with administrator privileges since my plugin needs to write and read files from the hard drive
