First, this is a good extension. But it's "half baked." They sell something that isn't 100% ready. You will face problems running this on your website. There are problems in coding, and scripting. Sloppy and clunky. I didn't see a solid and quality work, for a paid version. However, you can easily customize the look. If there is a problem, you have to wait for the next version to fix it. Until then you are stuck with an extension that doesn't work well. Visit their support forum, and learn how it works or how they work, before you decide to use it.
Are you talking our last RC or beta versions ? These versions could contains bugs. This is normal, for production only stable version should be used like Joomla!
