I presume the captchas are now requirement by Amazon?
I have no problem with added security measures, but I've tried logging on about 30 times, without success.
It's sometimes quite difficult to read the captchas. Is not is not possible to change the captcha if you can't make it out properly?
I'm pretty sure at least 15+ of my attempts were entered correctly, but apparently they all failed due to a wrong code or unknown error.
Quite frustrating even though I'm using Windows and a keyboard. Had I been using my shield, with just a remote to keep typing out these details, I would have no doubt gave up much earlier.
Not meant as a criticism, just an observation. Will try again tomorrow, when I'm feeling less pooped. Bit of luck, I will score first time then 

I had the same problem before, using this notice from the first post worked for me.

Captcha notice
Some of the captchas used by Amazon actually require you to put spaces in where blanks are present. Absence of spaces can actually invalidate an otherwise good challenge answer. Make sure to include spaces if needed.
