Have you tried reinstalling?
Patching? (obviously you've patched it to 1.04, but maybe try again. Does it work with 1.02?)
I wasn't able to find out much else on the internet. Another guy had the same problem with the same cpu you're using (p4). You might try asking Lucasarts for their opinion on it if reinstalling doesn't fix it.
