URGENT: labels and ratings lost from CS3 to CS5

Hi, I have been using Bridge CS3 for categorize my photos and i have instaled CS5 recently (i have the two now).

All the ratings and labels were lost. In jpeg files, in CS3 i can see the rating in the xmp metadata "rating" (in file info, advanced) but not in CS5 (the xmp metadata is there but without "rating"). In CS5 i can rating the photos with problems.

If i export (save) xmp from jpeg in CS3:
