No need to apologize. If you've not already invested much effort in setting stuff up (bboards, etc, from the admin pages) or customizing scripts, it's probably easiest to just dump your database, download new stuff, and redo it. Your nsd.tcl shouldn't need to change.
Once you've done this a few times it really only takes a few minutes to replace an existing version with a new one.
Of course, once you have an active site up and running or have built all your forums, project and that kind of thing it is a totally different story! My personal production site's a weird blend of ACS 1.0->3.2 :(
