I have german retail version of the game patched to 1.02. In game, version says: 1.0.13.40
I dunno why devs chose such version counting, but it's not so important. Much important is the question: are you sure you bought not a pirate copy but a legit one? Actually, some people said path 1.02 intergrated into Benelux release, also, it's partially confirmed that there is no 1.02 patch for english version.
