Wordpress Themes - WP Forum at BFA - Background Image for Page buttons no longer working

I am having problems with my background image for Page buttons no longer working. It did work, but for some reason it doesn't anymore, and I have no idea what the problem is. Now it just displays a solid color.

Here is my CSS inserts:

Code:

div#menu1 ul.rMenu li a:link,

div#menu1 ul.rMenu li a:hover,

div#menu1 ul.rMenu li a:visited,

div#menu1 ul.rMenu li a:active,

{

background: #aac95f url(wp-content/uploads/2009/09/gradient.jpg) repeat-x scroll top left;

}





/* Remove background from menu bar */

div#menu1 ul.rMenu {

background: none;

} 





/* Create spacing between menu buttons */

ul.rMenu-hor li {

margin-right: 10px;

}



/* Set Hover font to white */

div#menu1 ul.rMenu li a:hover {

color: #FFFFFF;

}

I am sure I have done something daft, but I can't figure it out. Any suggestions would be highly appreciated.
