System cannot find file specifed error
This error appears when the map compile has failed due to an error, or the current game configuration is not set up correctly.
- Check the error log in the Hammer Process Window to make sure there are no other errors that may have caused the compile to fail. If a compile fails, no .BSP file for the map is written, and the game will not launch correctly.
- If there are no other compile errors, you can try to reset the Source SDK game configuration.
