Gmod Water Texture Issue.

I recently had this problem.Before everything was alright.Then this:

Underwater:http://img209.imageshack.us/i/gmconstruct0002j.jpg/

Overwater:http://img339.imageshack.us/i/gmconstruct0001c.jpg/

So I was like, OK,lets reinstall Garrys Mod and hope everything is better.Nope.It was still their.
Pardon my stupidity but,please,don’t get to technical on me.

I fixed it thanks.

Reinstalling gmod never fixes anything because of steam cloud however deleting the gmod folder fixes most things.
