You might want to look more closely at the NAMD output. There should be a line "Info: Working in the current directory" that will tell you what NAMD sees as the current working directory. That way you can check to make sure that your file can be seen relative to that directory.

Best regards,
Dave

Your (retyped) error message shows the path incorrectly starting with three dots and the filename with a space in the middle.
