You might want to unistall the other one (I think that option is in the Start menu under programs). When the screensaver one is installed, it's automatically set to always start at boot, so it always gets in the way.
With the text one, just as a quicky way, you could start it by bringing up Windows Explorer, finding where you unizpped it, and double click. It'll open a DOS box and will go through the log in process. Then it'll get to a point where it downloads the new work and sits there. Just minimize and let it run...
As you become more proficient, you can hide the box and run it different ways with different programs (Setispy will let you start it up).
