Lines in CS's

I have a windows desktop, I believe it is 64-bit. In every custom story I play, there is at least one problem. In my own, my mouse does nothing. In everything else, the mouse doesn't work AND all of the white lines on the edges of the polygons are showing. This wasn't happening before I started getting into the nitty gritty of putting my level in the Custom Stories. I think there might be a problem in some .cfg file somewhere, but I'm not sure. No idea where to start looking.
