I'm having a similar problem in Calibre (0.050. My computer at work is running Windows 2000, could that be the problem? I am able to see the eReader through explorer, but cannot access it through Calibre, other than as a disc drive, which works. When I plug it in, I get the following error:
Job: **Get list of books on device**
**IOError**: (2, 'No such file or directory')
**Traceback**:
Traceback (most recent call last):
File "calibre\gui2\device.pyo", line 20, in run
File "calibre\gui2\device.pyo", line 122, in _books
File "calibre\devices\prs505\driver.pyo", line 327, in books
IOError: [Errno 2] No such file or directory: u'I:\\database/cache/media.xml'

When I try to send books to the device, I get this error:
'list' object has no attribute 'add_book'
Detailed traceback:
Traceback (most recent call last):
File "calibre\gui2\__init__.pyo", line 153, in dispatch
File "main.py", line 753, in books_uploaded
File "calibre\gui2\device.pyo", line 153, in add_books_to_metadata
File "calibre\devices\prs505\driver.pyo", line 442, in add_books_to_metadata
AttributeError: 'list' object has no attribute 'add_book'

Any help would be greatly appreciated!
