I haven't used eagle in about a month or so, but when I today tried to open one of my schematics, they were all gone including the board files! I have done nothing to my computer files and I have certanly not deleted anything. The only thing that I might have done is update it as I no longer get the message telling me to do so (I got v.6.2.0 light). This is such a disaster, what has happened?
