Need Help adding Audio file back into game

finished with new english voice overs.
I cant figure out how to get the files to play back in the game, this is what Im Doing
Step 1 - turn them back into Ogg files.
Step 2 - change file properties modify date to match original ogg files.
I can get the game to recognize them, but it wont produce any audio.
Anyone whos good with Ogg files, or modding this game, please help. I think it has something to do with the encoding the file BACK into an ogg .

files can be found here http://www.gamefront.com/files/22841991/CUTSCENES.zip

I included original Ogg files as well.

Okay, I managed to convert niadlys audio files ! Now I'll have to test them in game and include them into the next patch…

awesome, thanks for the help Wesp
