Impossible to analyze tracks imported from iTunes

Hello,
I imported my collection into Producer 7 from iTunes but when i try to analyze a track, i get the following message: "an unnamed file was not found". And I still can play my tracks without problems (except they are analyzed every time i play them)
Most of my tracks are from beatport in 320kbps.
Thanks
