Problem with MoHAA

Well, it’s not so much of a problem so to speak, but a frustration. I recently bought an ATI Radeon 9800 Pro and of course with the capabilities of this card I want to be able to use Anti Aliasing to get rid of jaggies and Antistropic Filtering to sharpen textures. Neither of them work. Well…it’s funny, when I have anti aliasing turned on MoHAA gives me just a blank screen but I am still able to hear the background music. When I have anti-aliasing turned off and just antistropic filtering turned on, the textures do not look ANY sharper (and I have it on 16x). I have the latest Catalyst drivers, and I am DYING for favorite game to look beatiful and run great. I honestly have NO idea as to what could be wrong…
