Hello, I need some help solving a communication problem with my prs-650. As soon as I connect the prs 650 calibre shows a message stating:

"Error communicating with device"

and if I open the show details message it says:

The SONY database at /Volumes/NO NAME/Sony Reader/database/cache.xml is corrupted. Try disconnecting and reconnecting your reader.

Traceback (most recent call last):
File "site-packages/calibre/gui2/device.py", line 67, in run
File "site-packages/calibre/gui2/device.py", line 287, in _books
File "site-packages/calibre/devices/prs505/driver.py", line 134, in books
File "site-packages/calibre/devices/prs505/driver.py", line 129, in initialize_XML_cache
File "site-packages/calibre/devices/prs505/sony_cache.py", line 94, in __init__
Exception: The SONY database at /Volumes/NO NAME/Sony Reader/database/cache.xml is corrupted. Try disconnecting and reconnecting your reader.


If you know how to solve this problem, please help.

P.S I am using mac osx 10.5.8 and my books are stored in a SD 16GB card.

Thanks
