Best way to solve missing Retrologue/Padshop?

Hi all. So after two long days putting everything back together after a restore, I imagined my setup only to find that retrologue and padshop are missing. I’ve already installed the Cubase update and Halionsonic 2 and all my other plugins. I’m now re-downloading the Pro 8 ISO off the website (as previously I’d installed from install files on an external hard drive). Should I uninstall Cubase? Or install the (presumably) old version off the ISO over the new one then install the new one again? Really confused as to how these two plugins even went missing in the first place :frowning: Thanks in advance for any help.
