There's a little confusion with the registration and "purchase" even though it's free but keep clicking. It's free, I promise.
No, there is neither a comment nore did I receive an email from you. Probably you tried to send an email via the contact form in english, which has been out of order (fixed it this moment).
Anyway, this contact form starts with:
"For questions about and problems with Scripts or Plugins
please add your comment to the respective page because
this way other visitors may benefit from our conversation."
And the comment-extension has been working fine all the time so - there is no problem with the support.
