Changing the stitches

Question

Is there any way I can change some of the stitches in my Virtuoso 160 myself? I know this can be done if I take it to a dealer, but I have the disk containing all the decorative stitches that came with the quilters edition machine I once had. It was destroyed in a fire and I replaced it with this used machine which had most of the same features. I cannot find any computer port to connect and change the stitches.
