Seems like only the CD version of the game makes use of SafeDisc. The DVD version seems to use something else that Protection ID can't identify but works fine on Windows 10.

I didn't know there was a DVD version!
Might have been only released in Europe and Australia. All copies i can find online is from there. (Including mine)
There are multiple DVD versions, some of which have SafeDisc and some of which do not.
