Mapping Error! :(

I am currently mapping for Garry’s Mod in Source SDK and whenever i open hammer. it displays an error message “Can’t force single thread from within thread!”
Please reply to this thread if you know a fix to this problem :slight_smile:

I don’t know what would cause it. I can say that you should google it, or reinstall source SDK.

I realize I’m bumping a year-old thread, but I’m having the same problem. A Google search turned up nothing useful, and face-punch search shows this as the only thread that talks about this. I’ve tried reinstalling source SDK, and got nothing. Any solutions found?
