Back on Traktor and can't redirect it to my Ext. HD iTunes folder

Back on Traktor and can’t redirect it to my Ext. HD iTunes folder

Basically as the title states. I have the iTunes folder in the tree menu on the right in Traktor but it is so outdated. So I tried linking it to my current iTunes folder in my ext. HD but it won’t allow me to click… Do I have to point it to an XML file? If so, I tried that as well.

Completely stumped here and never had a problem when I was on PC…on Mac now running Lion.

Any advice?

Edit: After reading for about an hour, I found I needed to rebuild my XML file for iTunes. Problem solved. Mods, you can delete this if you want.
