I am in CS6, OSx 10.8.3.
I have some old photoshop files, tif, psd, jog, etc. on a CD. When I try to open them, I get an error-108 and the file disappears from the finder. I have tried to copy to the hard drive, but I get an operation cant be completed, one or more items cant be fournd error-43.
I suggest trying to read the CD in a different drive.
CDs do degrade over time.
