My presets are not working and my instruments don't work in old projects. Help?

Hey nerds:)

This might be a to-parted question and I really hope you can help me with this one.

I recently bought a new MacOS device and chose to start fresh and manually install the only instruments, DAW(Logic Pro) and plugins I need and nothing else.

Everything has worked fine. There is plenty of sound.

Until I wanted to transfer my NI presets and trigger already made MIDI in Logic.

I found the Presets-folder on my old device, copied my presets and transferred them to the same location on my new device. In my head this should work.

The first problem I encountered was when I opened an old project and I tried to load a preset and nothing happened. The presets are there but it's like they're empty. How do I fix that?

The second problem happened when I went to check on the other NI instruments the project already were using and they generated no sound from the MIDI on their tracks. They show an exclamation mark. I have no clue what could be causing that, so please help:)

I really help you can help me out muy entire production catalogue depends on it…😥
