So you mean if I encounter on of these CAPTCHA errors after filling in all my details I should close the window and have another go? I´ll give this a go.
I would actually suggest to keep the verification as it will keep spammers locked out unless they run a very sophisticated neural image recognition script (pretty unlikely). Shouldn´t be too difficult to get the CAPTCHA working I guess and you´ll keep your program save from the scammers – at least the automated ones.
