[Bernd-81]

Hello and happy Easter!

i have two problems with DTM Race Driver 3:

1. i can run the game. but before course is loaded, the game crashes and i am back at the desktop.
why is this so?

2. how can i play the game without dvd. i made an image with alcohol 120 of my dvd and mountet it with daemon tools.
when i want to start the game, it says that i should put the dvd in another drive

now does anyone know a solution for my problems?

thank you
