ValueError: Error parsing Cloudflare IUAM Javascript challenge

Looks like it is broken again. I guess Cloudflare changed their scripts.

Oh, I should let you know, "ploplord" and "DukePlopsalots" are not my actual login credentials. lol

and... I found my issue. I was testing using -rn for a single episode number instead of multiple

-rn 9
vs
-rn 9-10

I knew the syntax and have used it properly lots of times, It just seemed to make sense that this could be done with a single digit as a possibility. Programming does not work that way. It is an exact science.

This could be marked as resolved or enhancement (to make it so you can just use range with episode number).
