Hi Ive recently purchase the Magix Music Maker MX premium, after installing everything incuding all the sound package i cant seemed to find VITA, as it keep popping up error message when i tried to use certain sound.
Did you make sure you downloaded all the extras from the 'Help' drop down menu "Upgrade Program/Upgrade Functions"?
I just checked my Music Maker MX Premium, and I have the Vita installed, I had the download version so I had to have downloaded this extra content through the drop down menu 'Help'.
