What do to solve the captcha automatically?

Hi.

I tried to search the web solutions to this problem but have not found anything.

I've been using the iBot for a week and when I presented this problem, I used the program [Only registered and activated users can see links. Click Here To Register...] to get the "Secret Key", but now no longer works. I also tried using ReCaptchaTrader, but not working.

So what I can do?
You, what do you do to solve the problem?

Seeking an alternative to pay.

ReCaptchaTrader works. But u have to leave ur PC alone and it costs a lot of credits per night. I think about 500 credits / night -.-
