Validation problem with an old version of chronoforms

After disabling the option "Show Tip Of The Day", Chrono Contact (3.2 V / 2010 / Chronoman) displays "Your ChronoForms at hotelnettuno.net install is NOT Validated".
I requested a new validation code and I entered it correctly, but unfortunately it is not recognized.
Being an old Joomla! 1.5.25 Stable, I ask you what is the best solution to solve the problem.

Hi Fritz,

The verification code should be saved in the "Parameters" section in v3 then you should head to the "validate installation" page and click validate.

You can send me more info using the "contact us" page

Hi Max, Right here on, I've written! I have repeat three times these steps, but I wasn't able to validate that website. You can find this code also on my Member Area. When I have time, I will clarify di thing. There being no other irregularities, in the meantime I leave it in that condition. Formally, the code and the domain name has been duly registered on your database.

Hi Fritz,

Please contact me using the "contact us" page so that we can discuss the issue in more details.

Thank you Max for your availability. I redid the procedure once again and I finally got the message in green color. This is the domain name that you can find on my validations (at the last). It was already previously recorded with a second-level domain name. It is now registered with the simple domain name (first level).
