Tech Issue

[Xavz]

I just bought KotOR, and it ran fine all the way through the Endar Spire, but after I reached Taris, it would barely run at all, the camera started acting strange, and the controls were messed up. Does anyone know why this would be?

All my specs except my CPU and graphics card are above recommended specs. My CPU is a 1.5 ghz P4 and by graphics card is a GeForce2 64 mb.

EDIT: I forgot to add that I am running every graphical option at the lowest possible settings.
