When running the voice response setup, sometimes an error would occur:
"Component 'SLMixerPro.ocx' or one of its dependencies not correctly registered; a file is missing or invalid." This is fixed now in v2012.4.152.
When collecting voice responses as .wav sound files, the sound files were not being saved and a "voice" data subfolder was not being generated. This is fixed in v2012.4.152
