As it is The Peasants Rebellion is completely unplayable in multiplayer because of save games not working and desync issues. I bought this game almost solely to play with friends over lan. Multiplayer really ought to get fixed, or atleast a mention should be somewhere that this game is only playable in single player.

I've read that The Shattered Kingdom works just fine, maybe make it an option to just install that instead of the expansion?

me all work savegames and i exit alls champaigns BUtT i can t go on multiplayer net-games in lan no any players :(

The multiplayer in TPR is broke and it was never fixed by the developers. You can't switch to KaM only, if you own KaM TPR, because the 'addon' is integrated in the main game.

The only chance you have is to wait for an unofficial re-release. Here you can find more information about the fan project: http://krom.reveur.de/index.php?t=kam_remake

The KaM Remake mod has fully functional Internet multiplayer! Try it out, it is compatible with the GOG.com version :)
