Hello all,
I recently discovered upon trying to open backups of older projects (spanning ~4 years of music) that all of my KK patches (made with KK2) have been reset to just a blank instrument window—no instrument, no dialog window asking about missing plugins. I figured this was due to the upgrade, uninstalled KK3, and downgraded to KK2.9.6 as many support threads have suggested but the problem persists.
