After some research into this on some less treaded boards.. it seems this might happen because of a update error waiting for you to say yes or no in the background.
To fix this just right click the desktop shortcut, click properties, then click FIND TARGET
The game folder opens up. You will see csi4.exe and gameupdate.exe... click on CSI4.exe
If it runs.. make a shortcut and drag it to the desktop :P If not continue below
"Black screen happens cause the game asks for permission
to access the internet in the background. So set permissions
in your firewall for the Gameupdate.exe & csi4.exe
(they’re in your install folder)." ----- THIS IS NOT ALWAYS THE CASE
Once you say no or yes then it continues. Of course in the same forum someone stated he just reinstalled WMP (11 comes with codecs so if you have installed codec packs...)
Everything needed to run the game comes with it, and ubi got so sick of cd protection this release as my ProtectionId finds nothing as copy protection.
So my advice is..
Make sure no codec pack is interfering.. if you dont know what I mean its prolly not
Try to open the game folder and run csi4.exe directly instead of it running the update engine (which is what the game came stock as running .. sigh ubi)
Reinstall as last resort but if you want email or pm me first
email or pm me with specs of the system and Ill help as much as I can!
Im personally having many other problems with the game after I got it running so just wait :P
Still a kick arse game though.
