did you guys leave it to load... as it does take a while and swaps screens about 20times, and if you do anything whilst it loads up it has all sorts of problems.
it should take a min to show a black screen saying "Loading..." after that let it flicker about and you'll hear music soon followed by the actual game.
Once it shows the main title screen you can then mess about
happened to me 2x before i realised it was probably something wrong with DBpro not the actual program.
works fine on my GeForce4 Mx 460 & GeForce2 Go! (Mx 100/200) ... which would be the only real similarity between you guys.
