Bug or lameass protection scheme in 1.7 patch?

[bugmenot]

Install game, patched it to Russian 1.7

Start the NEW game (any diff.level) -> Fight dragon=Can't fight it because I'm defeated as soon as battle mode shows up! (there is a text that my troops are overrun or something)...

I bought legally Nobilis version, it worked with russian 1.6.4 update and I used russian patch because I'm too lazy to put the disc in drive everytime I want to play...With patch 1.7 it *seems* to work but dragon after starting a new game can't be killed! What kind of bug is that? Hidden in-game russian copyprotection check? Silly...
