I have been working on a PCB layout for the past 5 hours. I closed the file and then tried to reopen it and I was shocked to see an error message saying "Decompress Failed". Now I can't open the file and all my hard work is gone. Is there any way to recover my file? If not, then I would say that this is a very badly designed software because the minimum requirement of any software is saving some sort of backup file for emergencies like these.
