I've attempted to use this with my Igo version 220.127.116.115512
I've done everything correctly I believe.
VAUTOV5.dll in root directory
tts_nua_v5 folder in root directory
the 2 tts.zip files straight into Content/Voice
The new voice options appear in my configuration screen, but when i press them I get no preview, and it reverts back to the previously selected voice.
Can anyone suggest anything?
