Only lets me select 2 detailed models

[SpectreXtreme]

hello, in the game setup it only lets me select a maximum of 2 detailed models, any more than that and it says my system is inadequate, which of course my system is not,

I am running an:

Intel core 2 duo at 1.8GHZ
2GB DDR2 667 Ram
and a Radeon X1600 Pro 256mb video card

any solutions?

instead of clicking the next button, you have to simply hit the "Enter" hey on your keyboard. otherwise you'll never be able to select more thank 2 models
