If your mobile add on is no longer working as it used to; it is likely due to the many upgrades to the devices operating systems recently. As the software developer isn't offering any updates, it is best to upgrade your site's software to the latest version.
The new version is pretty nice. The new one brings your site up to speed with Google, Bing, etc., and their wish that sites be responsive which means they work properly on all devices. It also has a zoom feature for images and product tagging for FB, etc., and product ratings.
You would need a new responsive template in order for this to work. You can either use one of our default ones (http://merchantmoms.com/templategallery.php) or get a new one pretty reasonably http://merchantmoms.com/templatedesigners.php. You may also be able to have your template converted to work well.
