cannot make it work (sign up page)

http://agentemusical.com/sign-up/

The above pages is the registration page. I am running out of email addresses to test this plug in. Once again, just like most of your plug ins. I am running into problems to make it work. Are these plugins in working condition? I am becoming very skeptical of the quality of your plug ins. Do you do a lot of testing before releasing? What about quality control for both instructions and code?

I have tried with so many emails to register.

1. I get throught the 1st screen where I create a username and password

2. In the next page where I am supposed to choose the subscription option the links are not active just text. On other cases I do not see any options.

3. I have the [accountform] shortcode in this page, but it does not show anything. http://agentemusical.com/cuenta/

Please HELP
