Dark Matrix.. if you are using v500 beta.. installing the Direct X 9 fix before or after the patch will cause game errors.. the v500 beta patch includes the Borg mini campaign, the nemisis add on, and the Direct X v500 fix as well as over 150 game fixes...
using anything listed above with v500 will cause the game to operate incorrectly... bugs, crashes, etc...
you need to specify that you mod is for Non patched version if you are going to advertise the Direct X 9 fix.
just letting you know..
