Accidentally patched - screwed up my dx files

[theman88]

Ever since EQ became required DX9 I havent been able to play since im using a Voodoo3 3dfx card (card doesnt have any compatible drivers) so i was playing Emu, clicked on the wrong icon one day and patched it =/ it loaded all these dx9.eng files and stuff like that, now when i log onto emu, the screen is all dark and text is screwy looking. Same thing happens when i get on eqlive w/o the dx9. Emu doesnt require dx9 now does it, I just screwed something up ? If so , any ideas on how to delete those dx9 files so it wont be that way all the time when i get on eqemu?
