Hello, thank you for the review!
I have checked the issue, as far as I understand, you bought the software in 2007, 11 years ago.
We have free updates for 3 years, which is written in our faq: https://www.chameleonsocial.com/faq.php
11 years have passed so no free upgrades are possible.
But of course you can still download the version you bought, please create a ticket.
Thank you!
Frank.
