WTF. Now i find this on ubisoft.com
Q: I have installed the 1.2 patch, but now when I start the game I get an error message that says "Please insert the correct cd-rom..."
A: If you are using a no-cd crack, you will need to to a clean install of the game. If you have any type of virtual cd-rom software (120% alcohol, daemon tools, ect) installed, you will need to disable or remove them from your system.
This REALLY pisses me off. This is their half-asses attempt to stop piracy, but at the same time cuts out many legitimate uses. This has to be illegal.
