So it's from a P2 card. In that case you should have a "CONTENTS" folder, unless it was renamed. Inside that should be 6 folders.
You will need to drag the "VIDEO" folder into the Premiere project panel and everything will sync up including the audio.
If you don't have all these folders, you probably won't be able to use the footage.
