Paths for final cut pro

Hi,

Just started using final cut pro.

Created myself an issue I hope someone can help me with.

I imported the files from my video camera into FCP

I then copied the files also to a specific directory on my system

I then erased the data from the camera and used the card for a new video

Now I deleted the project in FCP after playing around, understanding what I want to do

I now create a new project and click the import section to import the files again from the directory I have stored them in, but the files are all grey'd out, visible but not accessible.

Now I am stuck as I do not know on how to get FCP to import the files so that I can create a new project.
Any help much appreciated

Eddie
