Urgent : Oracle 8 Export Error

Question

Dear Sir,
I have Oracle 8.0.4.0.0 server edition running on Windows NT Server Platform.
From one week before i can't export the database.When i write the following
command
'EXP80 username/password File=<filename.dmp> buffer=80000 log=<a.log>
then following messages come.
'Message 206 not found. no message file for product = RDBMS80 facility = EXP
Release 8.0.4.0.0
Invalid format of Export utility name.
verify that ORACLE_HOMEis properly set'.
Now I want to create dmp file of the database / user. Is this possible ? If yes then please tell me how it can be done.
Thanking You.

here is my initorcl.ora :

# Copyright (c) 1991, 1997 by Oracle Corporation
# Example INIT.ORA file
# This file is provided by Oracle Corporation to help you customize
# your RDBMS installation for your site. Important system parameters
# are discussed, and example settings given.
# Some parameter settings are generic to any size installation.
# For parameters that require different values in different size
# installations, three scenarios have been provided: SMALL, MEDIUM
# and LARGE. Any parameter that needs to be tuned according to
# installation size will have three settings, each one commented
# according to installation size.
# Use the following table to approximate the SGA size needed for the
# three scenarious provided in this file:
# -------Installation/Database Size------
# SMALL MEDIUM LARGE
# Block 2K 4500K 6800K 17000K
# Size 4K 5500K 8800K 21000K
# To set up a database that multiple instances will be using, place
# all instance-specific parameters in one file, and then have all
# of these files point to a master file using the IFILE command.
# This way, when you change a public
# parameter, it will automatically change on all instances. This is
# necessary, since all instances must run with the same value for many
# parameters. For example, if you choose to use private rollback segments,
# these must be specified in different files, but since all gc_*
# parameters must be the same on all instances, they should be in one file.
# INSTRUCTIONS: Edit this file and the other INIT files it calls for
# your site, either by using the values provided here or by providing
# your own. Then place an IFILE= line into each instance-specific
# INIT file that points at this file.
# replace "oracle" with your database name
