Hello! worked in photoshop with psd file, suddenly shut down the computer. Can't remember when I saved before, maybe 5-7 minutes before. A reboot occurred automatically. When I reopened the file, it already consisted of one layer in black color. The weight of the file has not changed. And the preservation of its consistent shutdown of the computer. I. e. the file somehow merged all layers, remained before shutdown. How can I return a file to its state before this glitch? No copy. Program Advanced PSD Repair did not help, well, I wasn't counting, because maybe the problem is with the file other. Tell me what you can do in a similar situation. Thank You.
