When you download the Exporter, ("Blender_DTloveporter_0964.zip") if you are using a mac or a windows, just open it and it should extract it's self. If you are using a linux, you might have to download stuffit expander or some other .zip extractor. (I may be wrong. It might come with its own extractor too) When its extracted, if mac, run the script titled "MacInstaller(source).scpt" If windows, run "WindowsInstallScript.js" script. If linux, run "LinuxInstallScript.sh" script. The scripts should should place the files in the appropriate places for blender. I hope this helped.
