silent hunter3...cannot upgrade to v1.3

Well I am sorry to tell you this, but games bought from Thailand are very rarely original. The only way to be sure that the game is in fact the real deal is to go to the shop and find the collectors edition of the game and then make sure everything is in it.
I am not telling you this to be rude, but because I know. I went to Thailand myself and there was piracy everywhere. Even when I thought I bought an original game it was not. And those even had a real box, bad but nice done manual and a disc that seemed original.

But as you bought the game in good belief (that sounded awful ) I am pretty sure you can do something about it.
