A miss match or somthing?

[AmuletOfNight]

OK! So just trying to get the DirectX plugin to work, I go download rev 3661 and rev 21xx. I take the non-broken directx plugin out of rev 21xx and put it in 3611 and whenever i try to start it i get this:

"Can't open Plugins/Plugin_VideoDX9.dll, it has a missing function"

Anyway to fix it?
