I can't believe the amount of things (buying a new SSD, installing a new OS which could create issues with other software, installing one by one plugins back etc...) have to do to MAYBE have Pro Tools to work as it is supposed to be.
I've never encountered something like this with any software I used in the past (including big video editing software etc...).
But I have no choice.
I am looking forward for the industry to shift its standard to another DAW...
