Lotr - Bfme 2 - 1.6
 

Apparently your game.dat 1.6 version file for my backup from original is not working. After a few minutes of game play the game suddenly ends with the message "You have been defeated". I goggled it and it seems that behavior is related with a game protection to any backup disks and that sometimes it also happens with some original disks too. True? Thx.

It happens, true. But only if you don't patch it :) Same goes for Witch King - install BFME 2, patch it to 1.06, then install Witch King. Most don't do that and go for the direct install.. That's why..
