Unisstalled and reinstalled GMod and there are no gmod/gmod files

I uninstalled Garry’s Mod because for all the basic functions i was getting errors (opening spawn menu, popping balloons etc). So when I reinstalled it there are no files in the steam/username/steamapps/garrysmod/garrysmod folder and i dont really know what to do, im going to try to run the game but ill update once i do. that you for any help, mb someone could upload their gmod/gmod folder??? i dont know but any help is appreciated.

never mind… when i started it up it installed everything, gmod is really fast when there are no addons, so yeah… i wish i cpuld delete this thread
