Remove ruled lines in background of Runo Lite

I’m transferring my blog from wordpress.com to a www.ads-software.com site. I was able to use CSS to remove the ruled lines from my Runo Lite theme in wordpress.com, but it seems the same CSS is impotent in www.ads-software.com. Here’s what I used in wordpress.com:

#page {
background-image: none;
}

Again, this doesn’t seem to work in www.ads-software.com. Any help would be appreciated!

Thanks,

Grant
