Did I screw myself over?

I wanted to uninstall gmod and re-install it so I deleted the garrysmod folder in the steam folder and than I had to uninstall through steam and once i tried to re-install it, it says it will only take a couple minutes and only under 300 MB to install… obviously that is not correct but after installing again, the game crashes on starting up.

My god, does anybody actually read the other threads for once? The Engine Update broke Garry’s Mod. Garry already sent the fix to Valve, now we only have to wait.

GMod broken for everybody. Read the threads.
