Well, we had it up and running on the laptop (XP Pro machine with SQL 2005 Express), and we somehow broke it.  We were playing with skins and containers, and now we just get a server error.  Since we are just playing with it right now, there really isn't anything to loose, so we are looking at just wiping the install and starting over.  What files do we need to delete, and how far back do we have to go in doing this?  Do I have to delete and recreate the database?  Is it as easy as just re-running the DNN install package again, or is this a bad idea.  I knwo the Dummies book and many threads all say you cannot break the site while playing, but we have managed to do it a couple times now.  This one seems terminal to us, though may not be a big problem to people with more experience.  Suggestions welcome.

On a side note, is there a good article, post, tutorial, etc. on the file structure of DNN?  Where exactly is all the information fo rthe website located on the hard drive (this is a local install)???
