Lost Audio Logic Pro X

Lost Audio Logic Pro X

Hey guys,
Recently my hard drive crashed but luckily I had all of my logic pro 9 files backed up on an external hard drive.
When I got a new hard drive, I downloaded Logic Pro X and started to open my projects.
Everything is there but the audio (drum samples, vocals, etc.) are not recognized.
Is there any reason why this is happening?

Thanks,
Nick
