Okay i just fired up my game and I can change the AA to anything I want , while using the edited .DLL. I'm using the .DLL that references your desktop resolution for a display, and lists the in-game resolution as "Label".

Thanks but thats the one im using. The aa options are greyed out and wont let me change it to anything :(
Im not sure if the aa settings are stored in this dll.
Thanks for trying to help - ive now started to play it with aa off and its not that bad actually.
