Finally found out where and how to obtain the upgrade, and I've installed it. All programs I had installed previously work better. With 2 exceptions:
1. Microsoft Money is not compatible
2. Minutes Pro (A meeting minte software) doesn't work.

I can live without them both, and have found comparible equivalents to each.

I am very pleased and notice speed increase. I will be installing my WIFI within a day or two. Hopefully still smiling then.
