Setting the defaults

I uninstalled a slow motion mod for Gmod that worked, but was getting a bit annoying, so I uninstalled it.
I booted up the game and when it was done loading everything, there was no options, words, not even the console, just the background screen and the startup music. I tried uninstalling but it won’t for some reason. I remember there being a properties command that sets it back to the graphical defaults. What is this command?

Add -autoconfig to the launch options and run the game once. Remove it the next time you start it.

Thank you, I will proceed to do such.
Wow, uhm that didn’t work. Any other suggestions?

Oh NOW it works.
