Please Help Traktor is not accepting drag and drop folders into Track Collection.

Good Morning,

Im using a Macbook with OSX Lion .
My version of Traktor is 1.2.8 Pioneer T1 Edition .


I have just done a fresh install of Traktor where before hand I could drag and drop my whole external hard drive into Track Collection and it would load up my full 67 thousand tracks..
Now it seems as though it does not want to accept any tracks in folders or sub folders and will only accept tracks in their mp3 file state.

If anyone can point me to where Im going wrong this would be a great help

Cheers Kev
