Philipp']Ok, it seems to happen for fresh installations or when values are reset to defaults.
A bug report has been opened for this: http://bugs.vso-software.fr/view.php?id=787
The files are installed though (C:\Program Files\VSO\common\sounds), so in the meantime you can select them manually in the settings.
Thanks Philipp, I access them manually as you suggested, just had to find the English speaking woman, no worrys I am sure you will get it sorted. Thankyou.
