@EricOwens: If this is not a SO device, then you're doing something wrong.
One of the only way to end up with a blank screen with this hack is to tweak the screensavers folder while the framework is running (or to use some severely screwed up files as a potential screensaver).
It doesn't actually touch the original screensavers, so, even if the userstore is toast, a restart & everything's back.
Make sure the uninstall was actually successful, and do a full restart of your Kindle.
