When you run the backup .bat, whatever files are in your Database and Doctrine folders will be backedup to a new folder.
For example: before installing the mod on my machine, I restored my original database and doctrine folders, which I had copied when I first installed the game. These files contained both v1.01 and the soundvs.speed fix. I also wanted to have Bill's helodipping doctrine as a standard feature, so I included it with the "stock" doctrine files.
Then I unzipped the package into my DW directory.
I then ran the backup, which automatically creates seperate folders which preserve the Database and Doctrine set as they were at the moment you ran the backup .bat (it is your choice and responsibility what these files will be). Then when you run the "install" the mod files will be instated in your game. To go back to the files you backed up (presumably stock 1.01 plus soundvs. speed for MP with people who don't use the mod), run the "uninstall".
I hope this helps. PM me if you need further explanation.
