I purchased the enterprise version around 2000, and it turned out to be a big mistake. The domain binding was unexpected, plus there’s a link to their website (copyright) on every page, and removing it also costs money. Time passed, and I needed to switch to another domain. I contacted support since part of the site is encrypted in Zend Engine. The response was shocking - $100 for a single sheet of virtual paper compiled through the program? Isn’t that too expensive? Just imagine what their "free" support is like. I told them to take a hike. I installed OpenCart and a parser, and scraped my site. Keep in mind that if you buy this software with encryption, you'll end up paying like a cash cow because everything is locked down except for the themes.
