I've tried a few different browsers to register for MyJD via the website:
https://my.jdownloader.org/login.html#register
Each time I enter a valid email and enter the captcha I get:
"Unknown Error - Input Error"
<refer attached image>
I've been a GUI user for years, but want to try the Chrome plugin.
I try several captchas, and it's a different error when I enter the captcha incorrectly.
But this error does not have a lot of context, nor many hits when trying to search for others with the same problem.
Thanks
