I bought a Sony PRS300RCWB-30W ereader. It's gorgeous. It worked great until I sideloaded a pdf from Calibre. (Actually my usb drive had been acting a little funky when it was mounted at the same time as the ereader--and when I removed the ereader the usb drive worked great in Calibre.) Calibre started flashing and I got this error:

The SONY XML cache "'/media/gregory/495C-0DBA/database/cache/media.xml'" does not exist. Try disconnecting and reconnecting your reader.

Traceback (most recent call last):
File "site-packages/calibre/gui2/device.py", line 87, in run
File "site-packages/calibre/gui2/device.py", line 502, in _books

DeviceError: The SONY XML cache "'/media/gregory/495C-0DBA/database/cache/media.xml'" does not exist. Try disconnecting and reconnecting your reader.

After that the ereader is stuck in "loading" mode with the arrows in the middle endlessly revolving. I tried re-setting it. I removed the pdf from the ereader's files. I tried the suggested disconnecting and reconnecting. Nothing works. I am able to shut it down but when it comes back on it's loading again.

Any ideas? Thanks.
