I've been having the same problem with the Market Place. I've bought things here before without any trouble. Now I'm trying to buy an item and it keeps giving me a Page Not Found/Server Not Found/DNS Error. I know its not my ISP's DNS becauseI can resolve the secure.bondware.com domain, which is the credit card processing gateway for Renderosity. They are using some kind of scripting with .ez extension, which I have never heard of, but assume its PHP or ASP. There's got to be something wrong with the scripts. When you click Checkout, it takes you to https://secure.bondware.com/~poser/checkout.ez, which shows you your shopping cart contents. When viewing the source code for that page, the Make Secure Purchase button takes you to the same URL, but posts different variables. I've tried using two different Visa credit cards, and it returns the same error. This is getting pretty frustrating, since I need this item right away. Unfortunately, its a Renderosity-exclusive item, so I don't have any other options. I hope someone gets on this problem and corrects it soon. John
