RoA 3: Can't get to the worm queen

[His]

Good to know about version differences. Could You tell me how i can change game version in save game?(because i can't use my old save games in us version ). Maybe in us version i won't get that terrible dwarf problem and my mind will be finally at ease . I was able to watch movies , and kill the queen using savegame that You provided but still , i would like to finish mirror fight myself .
