FYI.

I managed to re-activate my Pronto account in the new site. This is what I did:

I requested my password by selecting "Forgot your password?" at the upper right of the new website. You will be asked for your email.

Your password will be emailed to you. The password I received did not work. So, I emailed back telling them this fact. Next day, I received an email with a new password that worked.

That's it...
