SBEP texture problems...

I installed Spacebuild, and the Space Build Enhancement Project, and encountered problems with the entities (texture, atmosphere etc.), so I copied, and pasted the matierials from The Spacebuild Gamemode into garrysmod/garrysmod/matierials
and the models to garrysmod/garrysmod/models. This did nothign exept mess up my revolver, and shell textures (I am not stupid I overwrote nothing)
Also the water is now purpel and black after i pickup the messed up revolver…
I then noticed even the PHX plates had a bit of color defriction…
I can’t post screens, but everything I metioned has turned to purple and black…

PLEASE HELP!!!???

EDIT: ONE MORE THING THE MAP WAS sbd_dynamic (to paniced to check the others)/goes to check/
