VoiceBox SoundMaker 2.0 creates sound files which are not fully compatible with System 7.5 and later. The file format is correct, but the files' "signature" is not what the System expects. To fix this problem, do the following steps:
Download VoiceBox SoundMaker Fixer 2.0.1.
Drag and drop the VoiceBox SoundMaker 2.0 application onto VoiceBox SoundMaker Fixer 2.0.1. This will update VoiceBox SoundMaker to version 2.0.1, so newly created sound files are created properly.
Drag and drop any existing VoiceBox sound files onto VoiceBox SoundMaker Fixer 2.0.1. This will fix those sound files so they compatible with System 7.5.
