I gave up with my legal copy, which I bought from Amazon and everything, I still have it here on my shelf, and just downloaded a copy and burnt that. The downloaded American copy worked fine.
I don't encourage piracy but the creators and distributors had reached the point where they said "Well, if you've got this particular edition basically, you're screwed". Money being tight I wasn't buying another copy, especially from the USA. I do own a legal copy I just wanted to play the darned thing!
It's a good game too, if a little slow.
Hope you find a solution that works for you.
If I can help let me know.
