I have the same situation. My windows is in portuguese and the folder you've mention is the same. All you have to do is edit the evars.rc or, if the theme have one, the themevars.rc, and change the path to your folder. If there isn't a path in this two files (it should have), take a look on all the .rc files for the configuration till you find the right place.
Hope that helps. :)
Best regards.
