How can I change: "PIONEER" folder (analysis files)

Please help.

I have recently moved from Windows to Mac.

I used Migration Assistant from an old family Windows PC to the new Mac, therefore the User on my new Mac was my Dad's name.

I downloaded Rekordbox and everything was perfect and my library was organised.

Since realising I can change the name of Users on Mac- I have changed my Dad's name to mine (seen as though it is my Mac).

I now get the message upon opening: Rekordbox cannot create the analysis file in the folder you specified in Preferences

The "PIONEER" folder (analysis files) under Rekordbox > Preferences > Analysis still shows the old location with my Dad's name, and this cannot be changed. Location below:

/Users/DadsName/Library/Pioneer/Rekordbox

I have read that uninstalling Rekordbox will not help. Can anyone suggest how I can change this analysis folder location?
