title: ImportError: No module named youtube_dl

  <p>Hey, um, the program overall seems to be working just fine when it opens with the cmd, but when I try to run it with F5 in the IDLE, it crashes with the error: ImportError: No module named youtube_dl. I have it installed and tried re-installing it aswell. This particular program works fine, but trying to write anything else using this module brings this error up even in the cmd window.</p>
