I managed to enable the plugin in UnrealEngine. But when I restarting the editor, I cant build the source and it says that I must build it manually. How can I do ? Also, in the stand-alone editor, I cant hit enter to confirm the key anywhere. I also applied the key in the VisualStudio file, like it says on your website.
(Edit: Licence-key question: The stand-alone editor opens without asking for licence-key now 
)
