Hi axel:

Hmmm... I've never had the problem, but I noticed on other sites that many people do have it (playing other games).

The general advice I have seen given is this:

DemoShield Runtime? Sounds like a problem with the installer.

Try this (if you haven't already) - Uninstall the game, delete the folder that the Uninstaller leaves behind, reboot, reinstall the game, and apply the patches. That should fix you up.

If you do uninstall the game delete the entire old folder that is left behind so that you can have a clean install of the game.

Hope this helps.

Cheers!
