Anti-Aliasing Stopped Working

[EvoCyanide]

Couple days ago it just kinda stopped working. AMD x2 4600+ 2Gb RAM ATi X1950XT Have the right line in EQ2.INI and Catalyst AI is disabled. The only way I can get it to work is if I hit Defaults under Performance and it drops my resolution down to 1024x768 then AA will kick in. If I run EQ2 at 1440x900 (my monitor's native resolution) it turns itself off, help!

Ok this is driving me mad, does SOE and their Customer Support apparently have NO answer to this problem? I've re-installed my display drivers 3 times now, set everything back to Defaults in EQ2 and still NOTHING. There's NO answer to this problem? Seriously? This is just ridiculous.
