My garrys mod dont work

when I bought Garrys mod + Css I installed them both and now when its finnished, gmod wont work… it says something “invaild texture materials/console/loading startup” I think… the problem is in the console but when i go to that folder, that file doesent exist there…

Plz help, ive allready started to reinstall…

well, have you started CSS at least once? BTW, theres a help forum, use that next time
