I'm attempting to install Numinix's Fast and Easy Checkout. but the first thing it says to do is download and install their CSS JS Loader. so i downloaded and the instructions say to add their stylesheet.css into the current template folder, ....???

now i'm not about to overwrite the stylesheet that is there now, no freaking way!

anyone have any advice on this?, maybe i'll combine the two stylesheet,

i haven't had much luck using their User Forum.

also, is it absolutely necessary to install CSS JS Loader, in order to use F & E Checkout?
