I, too, was a loyal Snapfish customer for years! You have devastated your website... losing precious photos and projects for countless customers. You need to... hire new software developers and new customer service agents if you want to survive. There are so many issues with your site, I don't know where to begin. Start by bringing back the old site and slowly make changes. If you don't undo the damage you will be out of business in a year.
Good luck!
