delete xml, and add new one? Seems impossible?

I created a xml file in rekord box 5 on my harddrive, but have since then decided to change the location of the xml file to a USB. I have tried to update the xmlfile to a new location, but with no luck, nothing happens. It is still the original xml file that is in the tree in rekordbox, and i just cant understand how to remove it. I want to remove that original file and then create a new one, but that seems impossible? I have now uninstalled rekordbox 5 and installed rekordbox 7 just to try to get rid of the old xml file but it just keeps following me, it just doesn´t disappear. I have uninstalled and installed rekordbox again and again just to try to get the file to disappear but with no luck. What I´m trying to do is to get the cuepoints from Mixed in Key that I have exported to the new xml file to appear in rekordbox. But since the xml file doesn´t appear I cannot reload the file to get the cues added.

Can anyone pls help me? I am using Mac
