You're welcome. The conf file looks correct. And the log file indicates it's connecting and is able to get the minitri:

However, the other three Downloading requests (which is not the actual download, but a request to begin the download; you'll see "Downloading" comes before "Connecting") never get the "Receiving file / Transfer completed" portion. It goes straight from "Waiting for response" to the next "Downloading" prompt.

It does appear to be requesting SEP specific files--do you see files with those names in your distribution center? Double check the products available and make sure there's distribution coverage for all of them. (Looks like I may need to set up an LUA again to play around with this.)
