metadata.db Error - it became 0 kb sized. Need to re-create

[ygreq]

Hey there,

I was using my calibre library on a macbook and it suddenly crushed while I was uploading some files.

I restarted the mac and tried to open calibre, but the program become unresponsive. After a few failed trials I figured I should try on a Windows PC.

After failing to start the library there as well, I figured I should check the metadata.db file. That is when I realized the file had 0kb size.

So how do I recreate the library? The only thread that refers to this kind of problem that I found is https://www.mobileread.com/forums/showthread.php?t=146839

The thing is I cannot load the library in the first place so I can restore it.

(I know that each file in the library has a metadata.opf file specially created for situations like these. How do I use this option to recreate my metadata.db file?)

Thank you so much for any input you may provide,

Delete the file if Calibre won't run (at all)
Right-click the Library Icon on the Toolbar: Select: Rebuild
And wait until the Task Wheel reads 0. (You should see the complete List appear)
