Help!

Recently i started having a wee look in worldbuilder to look at changing starting positions in certain maps, and fiddled about, doing the usual of pressing any buttons and hoping for the best, and now any random game i start has no trees, resources or luxuries on it, in short, all the overlays. Any1 got any ideas on how to fix it, short of reinstalling?
Cheers

Using a no-cd crack or pirated game can cause this problem. Use the original CD and it should be fine.
