@Effix I downloaded the files and had no luck. However, I decided to mess with the graphics a little. I changed my resolution to 1200x900 and put texture on low, anti-aliasing zero and left anisotropy on 2x. Left everything else as is, shadows, v-synce, etc. That got rid of the line down the middle. Sacrificed a little on the visuals but it took care of it.
