The developer was offering free versions of their paid product; Did you actually ask them if you could have just received it for free?

You've also neglected to tell us exactly what happened aside from the fact that it "makes a huge mess of the formatting".

If you're prepared to give him remote access to your computer, then why didn't you just give him access to your site?

This is purely blackmail and I won''t give in to blackmailers. Leave your review, I don''t care.

On the subject at hand, you did not give me any opportunity at all. All you said was that the mod did not work and that was it. When I asked you for details and the log in info to your forum to investigate your claims for myself, then you refused and insulted me too. Now, I understand your reluctance in giving out the log in info to your forum, but unless I develop psyching powers to read minds, there is nothing that I can do.

Anyway, my reputation here or elsewhere for that matter is spotless and speaks for itself.
