New version not matching audio to slideshows

Hi, with the new update I can no longer ‘match audio to slides’. I have tried installing the previous version but can only install version 3.8.8. How do i fix the issue of not matching audio to slideshow in the current update or how do I install the previous version to this update?

Further to my query in relation to ‘match audio to slides’ not working I am running FotoMagico 4.6.2 on a mac 10.9.5. Any help would be appreciated.
