Description of your issue, suggested solution and other information

Issue I have met before, previously solved with an updated version of youtube-dl (update accordingly to new standards on udemy if I am right).
youtube-dl first worked allright to download my last Udemy courses, then did not work anymore on this one.
I could download part of the video, then it crashed. When I tryed to resume it also crashes

Thanks for any help

I get the following error on the course's home page:
ExtractorError: Course 1016110 is not free. You have to pay for it before you can download. Use this URL to confirm purchase: https://www.udemy.com/cart/checkout/express/course/1016110/?discountCode=1804CHANGE11C2
I don't know how to debug or fix this without the credentials to access the course material

Yes, I use udemy-dl to download video courses I allready purchased to watch them offline. With my email/password it should therefore work (and it worked properly since last sunday)
