yup, i typed g_luck and it worked. the error that shows is

File input/output error:
filename.pdb

Then "filename.pdb" doesn't exist. You need to specify the actual name of your input .pdb file; "filename.pdb" is just a generic name that shows you how to use the program.

    If the program has given you a fatal error, then the program is
    correctly installed and working.  It is your input that is somehow
    wrong.  Without the actual error message, it's impossible to say
    what's wrong.
