Ubisoft released the promised Rainbow Six 3 : Raven Shield 1.5 patch December 9th, but they failed to mention their new copy protection scheme. It turns out that Ubisoft implented code into the RVS 1.5 patch which checks PCs for ANY clone or virtual drive programs and then fails to launch the game if such devices or programs are found. What this has in turn done is disabled thousands of consumers who use programs like Daemon Tools, CloneCD or Alcohol 120% from playing their Ubisoft games even if they have their own physical cds in an actual drive.
