[Mr.Abiff]

I have used Calibre for over two years and had no problems, but I just ran the update msi for v.3.19, rebooted the computer and cannot find the Library. If you can offer any suggestions, it would be appreciated greatly!

This is running on a PC's SSD drive, Win7 Ultimate (current updates) and Norton Security. I've had no significant problems other than Windows Explorer crashes occasionally. That is more of an annoyance than a problem (Microsoft "feature" ?) and I just restart the Win Explorer, after which it seems to work fine.

At the time of updating Calibre, I was running Beyond Compare on two other drives in the computer but that had no reference to the C: drive where Calibre resides. I ran the msi update file and afterwords rebooted the computer but when I went to add another title to the large Library, the only thing that showed was a blank screen. The title addition went fine but it was the only title that was displayed.

I searched the drive and the stated location of the Library (C:\Users\UserName\Calibre Calibre) was completely empty - not even the new entry showed. I then checked the Recycle Bin but that was empty also. Next, I searched for "metadata.db" over the entire disk but nothing was found by that name. I figured that if the Library had been moved, at least the metadata file would show up on a search. No joy there.

Yes, I know that I had ignored what I tell everyone else to do "backup backup backup" but that doesn't help at this point. I had updated Calibre many times over the past two years and never experienced anything like this. PLEASE, I really love Calibre and I'm not complaining - just trying to discover what happened so that I might avoid it in the future. I'm asking all you wise folks here for advice because I wouldn't want this to happen to others either.

So any suggestions you could offer will be greatly appreciated!
sincerely, Mr. Abiff
