I'm having an issue where upon talking to any other character in the world , Twinsen simply repeats his last said statement and then the game crashes.

Video below: Basically I'll hear the character I'm talking to mirror Twinsens last words (although the text is correct) and the game completely crashes/freezes.

I was playing this only a few hours ago with no problems, hence getting this far. I've tried uninstalling and reinstalling the game, and turning off/tweaking sound options, but to no avail.

Anyone who has had this problem and managed to fix it: your input would be greatly appreciated.

SOLVED:

This issue occurs only in Version 2.0.0.6.

If you kill the game process whilst it is attempting to do a voice file transfer (The intermission screen with Twinsen and Zoe and the progress bar down the bottom), this destroys the voice file transfer setup.

The result is you end up with corrupted VOX files.

To fix this, go to the directory below:

LBA 2 2.0.0.6 release: C:\GOG Games\Little Big Adventure 2\VOX
LBA 2 1.0.0.0 release: C:\program files\GOG Games\Little Big Adventure 2\VOX

Delete the EN_GAM.VOX and EN_000.VOX files from your game.

Now re-start the game and it should do the "voice file transfer" screen again. If this does not work, temporarily delete/remove your savegames from the SAVE folder elsewhere. The game should play the intro sequence as if it was a fresh install, and this will allow the game to do the voice file transfer again.

Once it is done, you may replace your saves and enjoy the game further.

I guess I'm in Quality Assurance for a reason!
Happy Oddyssey-ing!
