Demoshield have stopped working....

Hey!

I have got a critical problem with the installation of TW:Kingdoms expansion. When I first launch it from the CD and then press launch.exe the CD runs up smoothly as it normally should do but then it comes a error up which says the "Demoshield have stopped working... I can though run the setup.exe file from TW:Kingdoms folder and then it installs without any problems. But then after I have finish installing the game the Demoshield error shows up again.
The game worked fine for some mouth ago without any problems at all, either launching it or play it. please. I want to play again

Thanks in advance!
