Patience, Kaujoi. psiberpunk’s “assumptions” about your lack of knowledge are based solely on your posted error messages. Don’t be angry with psiberpunk just because you were not clear in your questions.
The error message:
is a Python error, not a DOS error. It means something is either wrong with your script, or what you typed into the python interactive interpreter (the prompt looks like this >>>) is invalid. So debug it. If you can.
