title: Udemy-dl access token is not recognised
body: <p>I have been recently trying to download my own Udemy courses, as I always did, with Udemy-dl software but I am having the following error:</p>
  <p>For about a week, when I do not use token I get this:</p>
  <p><strong>[i] : Trying to login using session cookie<br />
  [-] : Udemy Says: 403 Forbidden session cookie seems to be expired...<br />
  [i] : Updating session cookie..
  cloudscraper.exceptions.CloudflareCaptchaProvider: Cloudflare Captcha detected, unfortunately you haven't loaded an anti Captcha provider correctly via the 'captcha' parameter.</strong></p>
  <p>Also have these errors, but now when I use token. This is the command I used with token:</p>
  <pre><code>python udemy-dl.py https://www.udemy.com/course/python-course/learn/lecture/45714954?start=15#overview -k token.txt -q 1080 -o &quot;C:\My Files&quot;
  </code></pre>
  <p><strong>[i] : Trying to login using session cookie<br />

  <p>I have tried several times to empty cookies in by Mozilla browser, log out and in from Udemy.com and update the actual access_token at token.txt, but the error persists when I go back to python.</p>
  <p>What should I do?</p>
