I sent a ticket to the support for this issue and they gave me the following reply:
1) This is an older title which might not work well on the multi monitor setup.
2) You can disable all but the primary one before attempting to launch the game.
To do this, use the WindowsKey+P combination and use "Computer only". If this doesn't work, you need to disable the monitors in the graphics device Control Panel (right-click an empty section of your desktop to access it).
3) You can try a program called Dual Monitor Tools(DMT) which can be found here: <Links not allowed>.

I just copy the instructions for your convenience.
Step 1) Open the directory you just extracted the zip to
Step 2) Double click ?SwapScreen.exe?
Step 3) Right click Swap Screen next to your clock
Step 4) Left click Options
Step 5) Left click on the ?Cursor? tab
Step 6) Go down under ?Lock Cursor onto screen? and click ?Change?. Now select a key combination of your choice.
Step 5) Click close.
I realised, that I am already using such a tool and didn't know the possibilities of it. I am using UltraMon and configured a hotkey for locking the mouse to the active screen. This works for me.
