Well, I just tried it on my mste (tos 2.06uk) and it worked fine. Hell I got so far I even kicked Mum-ra's arse :).

So try the usual mumbo-jumbo, like booting the game from a clean system (no hard driver installed at all - hold alt), then hard driver with clean boot (no accs/prgs).

Just for reference I use hddriver with minimum caches (set all cache fields to 999).
