To disable "explode protection", you must:
1. Set in system registry a valid Cd-key, like from illegal copy or maded by keygen
2. Generate lotrbfme.dat by small tool from installer packege(exctracting in install process to temp dir)
Warning: i not have a game copy today, but i think its like as in Generals - datgen.exe and like in Zero Hour - datgenzh.exe
