Omerta won't run

[Sans-amour-shadowless]

Hello, I've installed Omerta fine, with my system being in Japanese setted and everything. But when I run Omerta it just says that it's "stopped working" and needs to close. Has this happened to anyone else? What do I need to do?

and btw, what is the 2nd option in the autorun program that starts with DVD because, when I try to run that, I get the same problem. I am using Daemon tools to mount the .iso and have installed the Directx that came with the disc,

please help, thank you
