PRS-650 and Calibre 0.8.37

[jeather]

I suddenly cannot get Calibre 0.8.37 to read the list of books on my Sony PRS-650. The drive shows up fine in Windows 7, I can browse to any book on the device, and Calibre seems to know that I have attached something, and I can send books to the device. I am using PRS+, but I have been using that for a while. I believe 0.8.35 worked last. I have restarted my computer since upgrading, and cannot think of any other changes I have made since.

Any clues/ideas/solutions? The error message is below.

Thanks.

metadata.calibre may be damaged.
Shut down Calibre (can't be running)
Delete that file (on H
you might run windows Disk check on that drive, tick ONLY "Automatically Fix File system errors" while you are at it.
When that is done.
Restart Calibre.
It will take a bit of time to scan and rebuild the list of Books Calibre finds on your reader.

That should help
