I can say again that this is a pirated copy. And even if there is a Buka logo on the box, don't be fooled, it's a fake. But it seems to play normally. True, you can't install patches for version 5 and play online.
And I wasn't planning on installing a patch for version 5; I just needed the first three parts, and the rest are on separate CDs and DVDs – a licensed copy from Buka.
