No… You set up the configuration for the wrong engine. :s
What configuration are you running under?

That’s how most people encounter the issue, it’s really just setting up the wrong engine for any custom config.

!!!PLEASE NOTE!!!
If your steam files are on a different hard drive than ‘D:’ Then in your text editor, Edit->Replace, ‘D:’ with ‘:’ Then hit replace all.
Example: Replace D:\ with C:\ -> Replace All
BTW: I wrote the garrysmod config. From scratch. (Pretty easy)
NOTE: Garrysmod config includes support for Spacebuild and Stargate. If you dont want them, remove: (from gmod config)
