Missing water texture (?) and game crashing on specific map.

[Ferelin]

Okay, so on ANY map that has water, there is no texture, unless you're under the water. I don't know why, and I can't find a solution :(

Also, there is a map called "gm_tf2struct" (it uses TF2 texturers, and is basically a copy of gm_construct. Search it on [url]http://www.garrysmod.org[/url]), and if I go to close to the water, you will (for a split second) see the purple/black texture, and then the game shuts down, with no message. It also has the bug with "No water texture".

Any help here? :(
