Crashes When Try to Exit or Complete Mission

[yumbelie]

Hey,

I've got a problem with crashes in Thief : DS - Basically, whenever I complete the training mission, at the very end - the game crashes. The games mouse pointer displays - and you can move the mouse, but thats it - just locked. The same thing happens when I click Exit To Desktop on the main menu. I've re-installed, upgraded my graphics drivers (I'm running a Gainward Geforce 5900 Ultra on a Nforce 2 Asus Motherboard by the way), and to no avail. Whats also slightly puzzling is that down in the right hand corner on the main menu, it says Version - but nothing beside it - maybe it's a hint?

Oh well, any help be majorly appericated as I'm about to turn the CD's in frizbees

Many Thanks

Yum.
