Problem Downloading a Custom Theme (no css folder included)

Hi
I want to create my own custom theme using theme roller, which i have
no problems using, but when it comes to downloading it there is no css
folder included. this is only the case with custom themes however, if
i download any of the default themes then the css folder is included
as normal. unfortunately there are no default themes that go well with
the style of my site.
Has any body else had this issue or know why it's happening and been
able to resolve the issue?
Thank you
Bobby
