tdlr : The chromedriver needs to be updated to the same version as your chrome browser.

Long Explanation :

Chromedriver is how the program communicates with chrome and controls it. Everytime chrome is updated the chromedriver needs to be updated too. Firefox doesn't cause the same problem. You can update firefox without ever needing to update the firefox driver. That's why I recommend using firefox instead of chrome.

If you still want to use chrome then you have to:

• Check your google chrome browser version by going to Settings > About Chrome
• Go to the chromedriver website and download the version that matches your chrome version and your platform (windows, mac, linux).

• Extract the zip file, copy the chromedriver.exe executable, paste it at this location : %localappdata%\LyndaCoursesDownloader\app-1.0.1 and click on Replace the file in the destination.

  You have to do this tedious process everytime chrome updates. This is something out of my hand. Again, this is why I recommend using firefox with my downlaoder. You don't have to do any of this if you use firefox.
