Custom Clock Helper applet missing after factory reset

I recently had to do a Factory Reset on my radio. In doing that I have lost the Custom Clock Helper applet and the screensaver configurations which I spent so much time creating. The radio's Applet Installer no longer offers the Custom Clock Helper nor is it listed on the LMS Plugins tab.

The Custom Clock Helper applet is available on Erland's website; I downloaded it but have no idea how to manually install it, and his Wiki link fails to connect, so I don't know how to fix this.

Any help will be greatly appreciated!
