Gmod crash when extracting

[Smex]

If you are talking about where do you extract it to, I just did it there but I doubt that is the right place, I think that you want to extract it to your Second garrysmod folder and then it should just slide into the right file areas if im correct. Try it out and see if that works.

I put the extracted file in the garrysmod and tried joining cityrp, but it still crash when extracting

It shouldn't have to extract. Make sure you extracting the file to garrysmod not just extracting it somewhere random and leaving it at that.
