I am trying install GYM Sitemaps & RSS module 2.0.4 to Artodia: Helion 1.2.0 (prosilver) -http://www.artodia.com/deluxe-phpbb-styles/helion.html

Could you please help instruct me as to how to implement this MOD for Helion?
It should be the last mod I will be adding.
It is installed but it is shoving (i believe footer) info out to the right hand column.

My skill level: Rookie (I can follow directions but do not know coding)
My site http://ssahs.ipage.com/newafk/portal.php?style=3
My phpBB Version: 3.0.10
Mods currently installed and working:
