It is a pity that I have to re-install tons of content on my new PC even the content folder for my MIR-PRO packs is on a NAS and already there.
I pointed ASSISTENT to the folder but it just won't regognize it as "already installed".
update:
in case of my MIR PRO RoomPacks, I could add the existing folder in MIR PRO, but I fear that any updates would not noticed since ASSISTENT still does not see the roompack as "installed".
