I'm getting the green light on the download attribute.

(Note: I haven't moved to secure level yet, just wanted to be successful with original setup first, then move per FAQ on secure relocation of download folder.)

My test free order gets message: "Page cannot be found. This error (HTTP 400 Bad Request) means that Internet Explorer was able to connect to the web server, but the webpage could not be found because of a problem with the address."

I didn't edit the configure.php files because I have the files in the original zen/download directory. Am I missing something?
