Forum:Problem with textures on Liara's Dig Site

Hello, i'm on my third career in ME, and have noticed each time i land on Therum (where you'll find Liara), a large majority of the planet's surface is just black, no textures or anything. the blacked out areas seem to be an area of some toxicity, as every time i take the Mako through it, i'm stopped dead in my tracks and receive a critical mission failure. i've found my way through the map a few times, but it's kind of irritating me, and i was curious if anyone else is having this problem? i'm playing a PC version, Downloaded through Steam, up to date, on an AMD Athlon 64 X2 6000+ @3.10Ghz, 1.5 GB DDR2 RAM (soon to be 3.5BG) and playing on a XFX GeForce 8200 MoBo with onboard Vid and sound.

Any help is appreciated!
