Regarding the captcha, it can be several things. First off, pay attention to what it asks of you. Does it ask for a single letter, a single word or a complete sentence? Also, if you are trying to cheat the captcha, then you will receive a cooldown period where no captchas will work. Cheating includes(but is not limited to) trying to guess the captcha before viewing the video, pausing the video and waiting for the captcha or trying to bruteforce the captcha.
It's always showing a "type in the nth character of this word" so far. I don't think I've tried to guess it, or have messed up many times. I must still be on "cooldown" because it still isn't working. Hopefully it won't be too long, just wish I had a number. I just hope I'm not making it worse by continuing to try every once in a while. Thanks for the response though.
