Hello There, 

I could need some Help, 

I have no Hardware of Pioneer, but I need Rekordbox for preparing Gigs on CDJ 2000NXS. 

I've tried to reinstall the whole program but it did not work at all. 

I've tried to your the solutions of other Posts, but something weird is going on. 

I've read that my Library should have a folder way with the Name: /Library/Application Support/Pioneer/rekordbox 

There is no Pioneer folder in my Application Support folder.. 

Please Help :<
