Texture Problems... HELP NEEDED

[PokemonTrainerWesley]

So, my Hammer crashed and once I entered back into it, several textures were wrong. Whenever I run the map, the textures are still how they should be.

I have no idea how to fix this, I've tinkered around things and searched the internet, but I still could not figure out the problem.

The image shows my dilemma, with the water being white.

(this has been solved and is obsolete, thank you for your help )

Have you verified the integrity of TF2's game cache?
