How to fix this error?

when i try to compile an example of devil's shadow system i get this dx7_setsystempropities. How can i fix it?

Hey PayDark, It's been a while since I have played around with Devil shadow and I have yet to upload this resource as soon as I find it.

If I recall it has something to do with including the DX7 dll and decls which should also be included in the package and place in userlibs folder.

I just uploaded a copy here from my userlibs folder with that particular function included, see if that works.
