Without knowing what you have exactly done and what specifically is the problem, we cannot help you.
Until you post more detailed information about your problem, I can only
refer you to this FAQ.
Please post a more detailed description of your problem including any and all error messages you encountered.
Also, describe where exactly did you unpack the game and what commands have you entered in DosBox (exact syntax, please; it's important).
If you have made any modifications to your DosBox.conf, please post a copy of its contents.
