the "neowin patch" changes a DLL on your computer (it is somewhere in the Windows folder).  It won't hurt to use the manual method of replacing the DLL (you can find instructions using google) and the patcher of Neowin's might also work, it depends how they do it, I suggest the manual option however.

If all fails, check that other people can use the themes and that they are for your version of windows as there are more and more for Vista coming out and not just XP ones.
