frustrated because no help for how to change the magentic screensaver to the one you want that you downloaded

I have really been enjoying the collections of wallpapers and screensavers. There are quite a few different themes to choose from, so no problems with variety. a fun and simple program to have on your computer..

I cannot change my home page from magentic. I have deleted it. restored defaults, changed defaults. reset home page to something else, searched for and deleted all files with magentic or incredimail.... homepage keeps revertening back to magentic. how do I change it!?!?!
