I've been using my site for a couple of years and have not had any problems. In fact, I had not even touched the site for a couple of months, then yesterday I went to look at it and the whole thing is gone!
If I need to reinstall, I have the MySQL database backed up a few months ago and also backed it up last year in the admin section of the blog. I also have copies of my old WordPress files on my computer. The weird thing is I hadn't touched anything in the site in a month or so. Also, when I FTP to the site via GoDaddy, I can see the database and all the files in what look like the correct places.
Any ideas? The site is: http://www.participatorysociety.org
