iTunes and engine problems!

Pls help!!! I’m completely stuck trying to link my iTunes onto Engine prime on my computer . I initially dragged music over to prime and it worked but lots of my album artwork was missing . I then tried syncing but it just won’t work, no files are found , I have deleted iTunes and reinstalled , I have the XML file share option set on iTunes.

What folder should the xml file be in ? I’ve wasted so much time on this now it’s driving me crazy .
