TPF Noob!
what happens if you click on any other files? such as jpg or tiff. maybe those photoshop files are corrupted. not familiar with the nbz file. what if you right-click on the photoshop project file (assuming these are project files you are trying to open) and select OPEN WITH....then point to photoshop and check the box that says always open with this program. at this point i would try copying photos from another hard drive to this one in question, then try to open them from this hard drive in question. if they open, and i'm sure they will, then you know it isn't the hard drive. sounds like corrupted files.
