Ships Underwater

[Tyharo]

I just upgraded to a new laptop and I installed civ 4 colonization. For some reason when I first start my ship is underwater, you can only see the sails. I continued on and all else seems fine such as land units. the problem only seems to be with water based units.
How would I fix this?

Have a look at the 'My Boats are Sticks' thread (among others).
