Mafia exits after short time

[ruedibaer]

hi there,

after starting mafia and playing the introduction or anything else, the game exits after a few seconds (20-60s) and switches back to the desktop. i´ve got no clue what the failure might be.

i seem to remeber that this error occured with the original cd as well.
anyway i tried all cracks from here.

Please help.

(i play the german version on win 98se, 1000 Mhz Athlon, Radeon 9000pro and 256 MB SD-Ram)

greets rüdiger
