Gmod Crashes After Messing up with my settings.

[Brikaas]

Well hello there I did make a stupid mistake like 1 month ago. I did change my settings same as this thread "http://www.fearlessrp.net/showthread.php?tid=7940" which was in posted in 2012 and I can't join server anymore It always crashes when I try to join. I did tried to delete and install the game but It did not worked so can I get some help ?

I wouldn't know a direct fix for this, but have you tried re-installing Steam and than Garry's Mod.
What you can attempt to do Is Right Click on Garry's Mod > Properties > LOcal Files > Verify Intergrity of Game Cache

Goodluck on fixing it
