Help w/ file formats
 

I'm running on os 9.2 and I just reinstalled basic. Before i did i would sometimes get files that were tagged "limewire document" which i couldn't use but i could view mpgs. Now all my mp3s are "cyborg documents" which i can open, but some are still "limewire documents". And now all the mpgs are tagged as "document" and wont open i tried opening them through quicktime and wmp which didnt work. Help please.
