I recently upgraded my site to Joomla 3.1 because hackers were constantly destroying the 1.5 site.
I bought this component and had errors installing it. I thought I lost my $92.00. I emailed the support team and got an answer immediately!
I gave them temporary access to the site and they had it up in running in nothing flash! They even set it up for me on my new Joomla 3.1 site.
They were AMAZING!
