Sorry in advance, that I can't give any good information, but I've hard that this game has given some trouble.
Can it be installed to hd without whdload? I remember that CP is very hungry for chip ram, so make sure you have as much free chip as possible (not sure if whdload changes this).
There are few threads about this game here a.org, maybe you can dig some helpful info out of them too (like this

EDIT: well, maybe not especially that one... ;-)
