Log and Transfer problem FINAL CUT PRO 7

I am working in final cut pro 7. I was tryign to log and trasnfer footgae I shot on a sony NXCAM, the cards I used where a Sony memory stick pro -HG duo. When i go to the transfer window i can see all the clips but as soon as I import them into the Queue they all have the red ! mark symbol. I belive I have transfered from this exact card before and have not had this problem before. Does anyone have a solution for me?
