[BHD:TS] EX cannot found "Team sabre dialogs.wav"

[Creator]

I'm working on a BHD:TS custom mission but I have a problem: I prepared some dialogues with the Dialog Editor(dialogs for MED) but when the mission gets to the point of those dialogues instead of playing them the game tells me: Ex Cannot Found "dialog.wav".
I specify that it is a mission in the jungle(therefore Team Sabre) and that the dialogues relate precisely to the Colombian campaign... for example one of the dialogues that I would need would be "TCmd001.wav".
Someone know the problem?
