Order of posts in stiva blog

Not sure, I bought a developers license version of the script about a month ago.
You did advise but I could not find the file you suggested I look at.
Im no coder so Im lost. It would be good to have the option of having the posts showing newest to oldest as most of my clients will be asking for.
I have spent two hours trying to do this.
Apart from this annoyance the script is just great.
