Im guessing you getthis error when trying to play any of the COC Missions and Intro Mission? I had the problem too..
The solution, if i remember rightly, was to dePBO the mission, open in Mission Editor and delete an object or something. PBO the folder up and it should work fine...
I know its a fair bit of work to solve the problem, basically i think that COC couldnt be bothered to release a new version that worked.
