I recently worked on a TIF file (from Capture 1) in Photoshop and just like how I would normally save it in a layered file. The next time I open my mac, I couldn't access the file anymore via PS, my image previewer, gimp or any other software. It keeps telling me that the file might be corrupt. I don't what I've done wrong as I just saved it just the rest of my other layered TIF files. The other TIF files are all working.
