Yep, when I try loading my NI plugins, I get the frustrating message "Loading issue. Plug-in not found. Please open the standalone application to rescan, or rescan manually in the Plug-in preferences." (I use Logic Pro, FWIW.)
I've tried "everything" (it feels), but when trying to solve the problem, I screwed things up all the more (I'm not that good about these kinds of things). I tried reinstalling Komplete Kontrol etc but to no avail. I've considered deleting "everything" (Logic, Komplete Kontrol, etc) in the hope that a fresh start will fix things, but I'm worried that this'll screw up the presets in my projects even if it turns out to solve the loading issue... (currently, when trying to play my projects, only Logic plugins work).
I know plenty of people have been in a similar situation... May I ask how you solved it? Preferably without screwing up already existing projects. Thanks in advance.
