Never mind (the issue noted below) … somehow the correct key came up on your site when I logged in. So this no longer an issue… Im registered. Can I get a refund for my recent second purchase of Paeon?

Hi
Paeon has been running on my site for over 10 years. I am unable to get the original key from the developer. So I purchased a new copy of Paeon and have a new key. The new key does not work … got message ‘key does not match’.
What do I do? Can you provide a key for the original? Can I reinstall Paeon without crashing my site? If so how?
Appreciate your help

Thank You
Mike
