[TippeX]

looks like a possible video driver issue..
i dont think the models are missing, more they are sort of 'off' from where they should be, like in the 2nd screenshot, im pretty sure the red circle should be around the circular hole in the piccie (up and to the left) and in the other, again up and to the left..

im pretty sure if it was a bug lots of people would have complained about it.. try upgrading your video card drivers, or experiment with the gfx settings in the game (if there are any) to see if that helps

you also do not state if this happens when using the original exe (so we can know if it is a possible issue with the crack), supplying more information does generally help, as if it isnt crack related then your best bet is to contact the technical support for the game
