What they are seemingly doing is filling in the water layers, even though I have the Land layer selected. What I mean is that it's doing is creating land bridges in water instead of rivers in land, if that makes sense. I have tried switching the colors around and nothing changes.

Help? I'm using CS6.
It's been a while since I did this one, but I think the problem is that you are on the land layer. You need to be on the land layers layer mask. It sounds like you are stroking the land layer, which would add more land rather than stroking the layer mask, which would remove land. Try clicking on the layer mask and then stroke the path. I think that will fix your problem.
