This just happened to me for the first time in two years I’ve had GMod about two minutes ago:
Any ideas what it means?
I clicked on Break In Debugger and it let the loading sequence for the server work for a few second, but after I got in the map it crashed and didn’t pop up any error boxes. I terminated HL2.exe in the Task Manager after that.
Intel Pentium 4 3ghz
