No problem, I love to help.
Taking a look, you might just be having some simple filename or directory path mistake, unrelated to x-cart. I think it is either a misspelling or directory permissions that won't let you write the file.
Looking at the css, you have:
Code:
background: url("../../skin/common_files/css/../images/head_linebg2.gif")
repeat-x scroll center top transparent;
And I think you need:
Code:
background: url(../images/head_linebg.gif) repeat-x top;
And then ensure that the path to the image is located at:
http://vibratorpleasures.com/skin/common_files/images/head_linebg2.gif
Let me know if that resolves it. Trust me I was very confused when I first started working with programs as complicated as x-cart, but it gets easier with time.
