We don't officially support different versions of games than the latest versions. I don't think it's reasonable to assume that we would, and if we did, we would probably be listing them on the order page. So what you did here was to order something we support, then ask for something else that we don't. I told you this would take some additional time, which to me seems reasonable as well, especially when you consider that we're still not even outside the 24 hours we publicize as our maximum order setup time (you ordered less than 12 hours ago, as of when I am posting this). ET in itself is a rare order that takes extra time to set up.
When I suggested that you send me some additional files to speed up your setup time, you chose not to, and send me an FTP link instead. That's OK. I haven't replied yet because I was passed out for most of the afternoon.
I don't know how many people you expect to be working here and able to fulfill your request, but we're still a small company. You're not dealing with an IBM or Microsoft (although perhaps they're bad examples, since support would probably be slower through them).
(I should also clarify that the two emails you quoted were send about 3 minutes apart, about 40 minutes after you emailed us. I sent the second as an amendment to the first, in the hope that I could save time over having to reinstall the game, then if necessary patch it to the version you wanted -- I haven't had time to fully investigate what it would actually require. It has been about 6 hours since then, and as I said before, I spent most of that time unconscious.)
