Lightroom 5 help to restore a catalog

I have a back up copy of a catalog on a hard drive. When I open up the catalog at the top first line under catalog it says there are 6600 photos, however when I scrol down under folders for that drive all the folders have question marks because non of the photo's can be found.  I tried importing but can't find them on the hard drive.

I can see the photos though in Windows explorer on the drive.  Is there any way to get an actual person to help me recover the files?

Thanks
