I saved a psd file that I had been working on for days. I was saving as I was working on it, just in case. Yesterday, I saved it onto my desktop, and closed the file. I went to open it directly afterwards, and I got the error message: COULD NOT COMPLETE YOUR REQUEST BECAUSE OF A PROGRAM ERROR. I went to the forums and tried some of the thing recommended. I tried opening it on CC 2018, 2017, 2014 all upgraded, including the Cloud, and it won't open my file in any of the versions. I am on a Mac OS Sierra 10.12.5. This is not the first time this has happened, it first happened in January, right after the new year, with about a dozen png and psd files that I had been working on at that time, that I now can't use or know how to open. They open fine in Preview, all the detail is there, but will not open in photoshop. Some of these files have massive amounts of layers, just thought I'd add this. To top this off, photoshop would not let me save some items in png format, and I couldn't figure out why, I thought maybe too many layers to compress, but I'm not savvy. I have been trying to find answers for weeks now. I can't use or open the files. I am completely turned off by the Customer Support out of India. Is there anyone who can help me with this. Thank you.
