Cannot get any CSS files to work in a MCV setup

[niggles]

Hi,
I can't seem to get any CSS files to work in my site which has an MVC type structure. I suspect there's conflicting re-writes going on.

Javascript files work with some success i.e Jquery refuses to play nicely no matter what and isn't available to the libraries that need it, but a lot of other files do work fine.

Great bit of coding though!
