what version/distribution is my game??

[Mac59]

Hi,
I have just purchased a boxed version of Kings Bounty online (English it seems).
The game installs under: ..\program files\1c company\king’s bounty
When run it displays version 1.6.4 (build 34,502).
I tried the update to version 1.7 (multi language) and (after a clean reinstall) 1.6.5 atari.
Both updates cause the copy protection to fail, and not recognise the DVD.
What is my version of this game??? What patch should i use?

i feel a little cheated...
