Micro prism missing patches

Stevie boy

I have been working with old versions an upgraded an theres a couple of old tracks I want to complete , on opening now some of my midi won’t play because the patches are not there in micro prism , did they not carry them all forward through versions ? I believe this is why it can’t find them an it’s scanning and telling me to re start standalone or reinstall but there not in there either . Can i not have all the patches / libraries or versions so it loads ? Or I am totally wrong with the issue ? Please help these parts are integral to my songs . Stevie
