Someone posted the same problem in another thread.
Customer support is not available on the weekend. I recommend that you save your project as a .scribe file and also publish it as a powerpoint file, while you wait for customer support to reply Monday.
Also, it may be a good idea to raise a support ticket.
See the support article- Can't Publish to YouTube.
Render the project locally and then manually upload.
