Hi, I bought it in France and I just hate our dubbing. Luckily for me our version is a "multi" one so I just had to go and tweak a little registry key to get it to run in English. Just run your regedit, and search for "CSI" continue to search until you get a key located in the
and in this one you just have to change from whatever it is (French in my case) to English and voilą!
Hope it helps.
