My slideshow stopped working. And I have not added anything to the site before it stopped working, and I cannnot login to get the updates. My site is legghornsandshakes. From what I see, I can buy it again, which seems about the time you guys setup the new update. So do we have to buy it everytime you guys update it? and why would it stop working about the same time?
