I got Guitar Rig 7 pro in a bundle so I sold my version of GR5. I think this was a mistake/ I did not open all my old projects and save off the GR5 presets tweaked/used. So now if I open the project (in Reason) with GR7 installed, it shows a missing GR5 plugin and no way to use GR7 to load these settings. I think I need to re-buy GR5 just to have handy if I need to re-open old projects, or is there another way to do this?
