Getting frustrated - Commandos II

[StephKort]

Ok...heres my problem..
I already searched for a solution but i didnt find any, so
dont flame me.
I copied the commandos CDs...game installs fine...
i try to start the game, crash in intros!!... fine
figured it was my sound card (onboard), turn of
musica in the cfg file...started the game..it WORKS!!!
But if i want to start a single game and click on the mission
START, I just see the loading screen for 2 seconds and am set
back to the main menu...What is going on?

Anyone able to help me???
