Happened to me, too. A network lock on a company on my server turned into every one of my company files on my shared drive being corrupted. NO IDEA how that could happen. I am having to restore every single one of my company files out of backups that were created when the companies were opened in each of the updates. I am losing hours, if not days, of bookkeeping on every client, as well as my own time restoring files. It is probably going to take me 3+ days to get through all of this and my staff over a week to duplicate work that has already been done and lost, all the while I have tax returns piling up...
