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.
Brand new interactions and interfaces. 
Easy to use and quick to get started. 
Please see this post for ways to recover your file:
