I've have the same problems, even though I live in the US.
Even when I get the captcha to come up, it crashes my browser when I click the audio button.
It's really to bad soney won't allow people outside the US to use TTS either.
I guess I can understand it for people who don't speak English, but they should at least allow English speaking people who don't live in the US to use that feature.
Calling soney is a bitch seeing as they don't have their number listed anywhere.
I had to call them once because I needed them to send me a password reset e-mail because my system wouldn't send it, and I had to sirch on lots of forums before I found the number to call.
They seemed open to the idea of TTS doing more than it does, and we can now check our trophies and a few other things I suggested to them on the phone that day.
If you had TTS, you could still redeem giftcards and promo codes seeing as that part of the psn store talks; for some weird reason...
Sorry for your troubles.
I almost went over to xbox myself, but so far playstation has all the games I want and the interface works pretty good; for the most part.
Now if only they'd allow us to lock the order of the items on our home screen...
Later!

also had the same problem with the web site until I got someone else to do the visual puzzle. same with the app. I like the ps4, but sony being lazy with their work on the tts and other stupid decisions is why I kept my xbox around in the first place. its time for sony to get back to work on this broken tts
